Technical Details
Here at Superfeet, we try our best to create awesome products that help get people back on their feet so they can enjoy life to its fullest. We recognize that some people have various allergies to different chemicals, materials and adhesives – we strive to manufacture products that do not contain any unnecessary chemicals, materials or adhesives.
We utilize quality materials throughout our manufacturing process and have tested our materials extensively. We test to ensure that all our products meet the requirements contained in the following regulations: CPSC requirements for Lead, heavy elements and Phthalates, the European REACH Chemical restriction standard and also California Prop. 65 hazardous chemical list.
Allergenics are a unique field and are based on individual cases. Given the large range of potential allergenics and how they affect an individual, we cannot test for every case. We endeavor to make our insoles as hypo-allergenic as reasonably possible within the confines of our manufacturing process, but since every allergy is different – whether caused by direct contact, proximity or in combination with other products – we cannot guarantee to you that our insoles are 100% hypo-allergenic based on your individual concerns and sensitivity.
Latex is one of the most common questions we are asked about. We manufacture our insoles and packaging with no Natural Rubber Latex (NRL) ingredients. With no FDA approved test for natural rubber latex we work closely with our supply chain to document that this ingredient is not used in our insole products but ultimately have to rely on our supply chain for this information since we cannot independently test for this. Please note however that some of the shoes we manufacture may or do include NRL ingredients at this time.
If you know that you may have a chemical sensitivity, we recommend that you try one of our Heritage products (GREEN, BLUE, BLACK, BLUEBERRY) as these insoles contain the least amount of materials or potential irritants (however, we are not representing that these Heritage products are allergen free, they are just the products in our Superfeet line that would have the least amount of allergens for most persons). The Heritage products are composed primarily of Polyester fabric top cover, Polyethylene foam, Polypropylene plastic cap and an EVA based adhesive. Our other insoles and footwear, while similar, do have additional materials and adhesives and again, depending on the nature of your sensitivity and individual case, may not be an appropriate choice for you.
Please discuss with your health care provider if you have any further questions or issues, as they are the most qualified to guide you in choosing the best product for you and your individual circumstance.
Some Superfeet insoles may feel different than you expected. This design is intentional — the contours of each insole are positioned to have maximum impact on the way your foot functions as you move. However, your comfort is key — if the insole feels uncomfortable to you, try a different Superfeet style.
They’re made with women’s specific dimensions — a slimmer heel cup and a shape created for the proportions of a woman’s foot.
Yes! Check out our Superfeet RUN Series insoles.
We also have insoles designed specifically for:
Hiking
Hunting
Athletic footwear
Casual and dress shoes
Snow sports
Hockey
And, we make footwear with Superfeet shape inside.
First, our sympathies. Really. Plantar Fasciitis can be a super painful, debilitating condition. (Want to know more about Plantar Fasciitis? Read our take: Plantar Fasciitis Explained.)
Second, we’re here to help. Adding the Superfeet shape under your foot can reduce stress on the plantar fascia and get you well down the road to recovery. The deep, structured heel cup of our insoles cradles the soft tissue of your heel to provide an extra layer of protection from hard surfaces. The Superfeet insole for this condition depends on your footwear and personal preference, but start by searching our Pain Relief insoles – those are built with features specifically intended to help with foot and heel pain. Another tip to help relieve or prevent heel pain: wear Superfeet insoles in all of your footwear, all of the time. More than half of Superfeet users own 3+ pairs of Superfeet insoles – different styles of Superfeet insoles for different shoes.
As all feet and people are different, there is not one specific insole designed for flat feet. Our proprietary Superfeet shape adapts the flat surface inside your footwear to the contours of your foot, making your shoes (and you!) remarkably comfortable. To pick an insole, start with your activity and footwear (i.e. if you are hiking, start by looking at our hiking insoles...if you are running, start by looking at our RUN insoles, etc.)
For general, non sport-specific use, you may find that our insoles with the most flexible, accommodating shape (like FLEX, BLACK or COPPER) may feel best for you.
The drop of the insole is approximately the thickness of the stabilizer cap—this thickness varies depending on the insole style. We do not make insoles with a zero drop.
Yes, but be particular about the style of Superfeet insole you choose. Avoid using our BLACK, CARBON, COPPER, BLACK DMP and YELLOW insoles as features on the bottom of these insoles can damage waterproof liners. Our hiking-specific TRAILBLAZER insoles are a good choice. Note: over time, most insoles will conform to the heel of your footwear and can cause wear through the lining. Superfeet offers no guarantee against the side effects of the insole wearing through waterproof liner.
Yes. All our insoles are vegan, except for the insoles with merino wool top covers. We recycle merino noils — wool fibers too short to be used in fabrics — to create our felted merino wool top covers.
Yes.
Sizing and Trimming
wideGREEN are designed to accommodate a foot width of Men’s 3E to 6E.
No. Here’s how to bake and fit your Superfeet:
1. Fit Superfeet insoles to your un-baked skates.
2. Take the Superfeet insoles out of your skates.
3. Bake your skates.
4. Put the Superfeet insoles back into your skates AFTER they’ve come out of the oven, but BEFORE you put your foot in.
5. After you've put the Superfeet insoles in your skates, follow the required directions for fitting your specific brand/style of skate (cooling period, etc.)
6. Hit the ice!
Our CARBON Pro Hockey and YELLOW insoles are specifically designed to fit well in hockey skates. Hockey skates are sized on a different system than footwear — the sizes for hockey skates is generally one size to a size-and-a-half smaller than typical footwear. To get a good fit, start by choosing a Superfeet size based on your footwear size. However, if the difference between your footwear size and your hockey skate size is two sizes or more, consider going down a letter size in Superfeet to better match the size and fit of your skate. Note: in many retail locations, the skate size is listed on the packaging for our hockey-specific insoles. In that case, use the skate size listed as your guide.
Absolutely. Full-length Superfeet insoles are supposed to be trimmed to fit in your shoes.
Here’s how:
Our ¾ insoles are not meant to be trimmed. Just drop and go.
Choose the corresponding letter size next to your usual shoe size on this chart:
Superfeet insoles are in letter sizes that span one and half footwear sizes. All full-length Superfeet insoles should be trimmed to fit your footwear.
If you are on the cusp (aka between sizes) and aren’t sure which size to choose, keep in mind it’s most important that your heel fits well in the heel cup of the insole – it should be “in” the heel cup, not “on” it.
Footwear
For most of our footwear styles, handwash with mild soap and lukewarm water. Use an old toothbrush with soft bristles if needed. Air dry. Some Superfeet Footwear styles are made with leather. For footwear styles with leather, you may wish to use a special leather cleaner. Leather cleaning solutions, sprays and pastes (brands like Kiwi, Nikwax, etc.) can be found at most drugstores.
Absolutely. Feel free to swap out the Supercork insole with most of your favorite Superfeet insoles. You’ll likely need to trim the Superfeet insole to fit well in the shoe.
Not at this time. Our smallest size Women’s footwear is a size 6; the smallest size in Men’s is a 7.
No. All our footwear styles are standard width only.
Cleaning and Care
We have a 60-Day Satisfaction Guarantee.
Superfeet guarantees its products will provide satisfactory improvement in comfort and performance. If you are not completely satisfied with the Superfeet product, you may return the product to the Retailer within 60 days of purchase. Products may be returned to the Retailer’s retail premises or by post in the manner indicated on the Retailer’s website. This guarantee is not valid for discontinued products, or products that have been customized or modified improperly by the Retailer or that have been damaged while being so customized or modified, products damaged by misuse, abuse or improper trimming or cleaning methods.
Most often this is caused by improper fit in your shoes. First, be sure the insole is trimmed correctly. Remove the Superfeet from your shoe. If you see creases in the foam at the toe or sides of the insole, you may need to do some additional trimming. Slightly trim the edges of the insole. There should be a small gap of 1 to 2 mm (that’s about the width of a nickel) between the Superfeet insole and the end of your footwear. If the squeak persists after trimming, try adding some talc or baby powder under the Superfeet insole.
Should the squeak be absolutely relentless, give us a call at (800) 634-6618 and we’ll help remedy the issue.
It’s a good idea to clean your Superfeet insoles occasionally. Handwash with mild soap and lukewarm water. Use an old toothbrush with soft bristles if needed. Rinse well, remove excess water with a soft towel and allow to air dry, but not near a heat source. DO NOT MACHINE WASH OR DRY — the results aren’t pretty.
You can count on reliable comfort and support for up to 12 months or 500 miles, whichever comes first.
Basics
Start with your footwear. What shoes are you putting these in? What will you be doing in these shoes? Use the filters in our Insole Shop to filter the choices by your footwear type and activity (you can also use these filters to sort insole choices by gender, product line, thickness, materials, etc.).
Your comfort should be the key decision-making factor in deciding which is the right insole for you. To try out demo insoles in your shoes and receive an in-person recommendation, visit one of our retailers.
The short answer:
Superfeet insoles help you move more comfortably so you can spend more time doing what you love.
The longer version:
Superfeet insoles provide Comfort, Pain Relief and Performance. You can dramatically improve the fit, function and feel of your footwear by adding a pair of Superfeet insoles. The Superfeet shape can reduce foot fatigue and help resolve common foot and lower leg injuries, like plantar fasciitis/heel pain, shin splints, patellofemoral pain syndrome, Achilles tendonitis, IT band syndrome, etc. Finally, you can enhance certain aspects of performance, like going farther or faster, with Superfeet insoles in your footwear.
Our shape. We use cutting-edge technology and innovative materials to take elements of our proprietary Superfeet shape and create insoles tailored to specific activities, uses and footwear styles.
Superfeet insoles work by interacting with your foot in ways the ground or a traditional shoe can’t.
The human foot is designed to adapt to uneven, natural terrain. Our world has become hard and flat, thanks to man-made surfaces like sidewalks, tile floors and paved roads. For your foot, it’s exhausting, and can be painful. Our proprietary Superfeet shape adapts the generic, flat surface in your shoes to the contours of your foot, making it easier for you to move. Learn more.
You! Superfeet insoles enhance the fit and feel of a wide variety of footwear, from high heels to hockey skates, hiking boots to high-tops. There’s a Superfeet insole that can help you feel great doing the things you love, whether that’s hitting the trails for a day hike, carving through moguls on a black diamond or browsing your local farmers' market.
