FREQUENTLY ASKED QUESTIONS

Absolutely. We sell regular ski boots with the manufacturer's stock liner — fitted properly, at no extra charge, by our expert boot fitters. Custom insoles and liners are upgrades you can add whenever you want more comfort, support, warmth, or precision: now, next season, or never. Either way, you get the same fitting expertise.

Yes. Our liners work with all brands and models of ski boots — you do not need to buy a new shell from us to get the custom liner.

A resounding yes. Ski boots are the most pivotal piece of equipment for your overall skiing experience — even as an intermediate skier hitting the slopes occasionally, the right boot dramatically enhances performance and enjoyment.

About five minutes from pour to solid. A boot fitter manually injects gel-like memory foam into your shell while you're standing in it. The foam solidifies in five minutes and you can ski on it immediately — no break-in period.

The X Heat is our all-around performance liner with an injection-molded cuff and power-channel tongue. The R Heat is a lower-volume FlexFit liner for high-performance skiers 100+ days per year. The C Heat is a softer, relaxed-fit liner with a sculpted lower cuff for calf comfort. The C Wrap Heat combines foam injection around the foot with a moldable EVA wrap around the lower leg, built for skiers with larger calves.

Surefoot liners last dramatically longer than stock factory liners — most customers get multiple seasons of use even at 100+ days per year. Because the foam is manually injected and tailored to your foot, they don't pack out the way factory liners do.

Yes. Because the foam is injected while you're standing in your own boot, the liner forms to your exact foot and ankle geometry. Hot spots, pinch points, and packed-out-heel feel disappear. Bring the boots back to any Surefoot location any time for a free adjustment.

Every Contoura liner ships with an integrated heating element built into the toe box. Heat is optional — pair the liner with Surefoot Winterheat batteries for an instant warmth upgrade. Add the batteries at purchase or any time later.

Yes. Bring your boots into any of our 29 locations worldwide for adjustments. Our Absolute Fit Guarantee: we will repair or replace your liner at our discretion at no expense to you if you are not completely satisfied. The guarantee does not cover natural material breakdown from extended use.

Surefoot Custom Liners and Orthotics are exclusively available at our 29 Surefoot stores worldwide. Each store is part of our family-owned, family-operated business — not a franchise. You won't find our custom products at other retailers, but we welcome you to visit us for a personalized fitting.

Insurance coverage for ski boot liners is rare — liners are a comfort and performance product, not a medical device. Custom orthotics are more commonly covered when prescribed for a specific condition. Ask your Surefoot technician for an itemized receipt; HSA/FSA reimbursement depends on your account and medical justification.

Our contact digitizer uses 538 pressure-sensing pins that gently rise to meet the bottom of your foot, capturing two things at once: your foot's complete 3D shape — every arch, curve, and contour of the soft tissue — and how your weight actually distributes across it. Most foot scanners are flat, so they can only measure pressure against a hard surface; they never feel your foot's true form. That combined picture is what lets us mill an insole that matches your foot exactly.

No. When you order, you'll choose the insole your shoes are built around: a Conforma insole — our site helps you match one of three arch heights to your foot — or a fully custom milled orthotic.

Custom requires a foot scan, but if you've ever been scanned at a Surefoot store, we already have your foot data on file and we can mill your custom insoles without a visit. New to Surefoot and want custom? Stop by any of our stores and we'll scan you in minutes.

Conforma is our ready-to-wear insole line, available in three arch heights plus a narrow fit — you pick the profile that matches your foot, no scan needed. Custom is a one-of-a-kind orthotic milled from a precise scan of your feet, matching every contour exactly.

Think of it this way: Conforma fits your arch type. Custom fits your feet. And you can start with Conforma and upgrade to custom anytime.

Generic shoes are built for an average foot, with a thin foam insole as an afterthought. Surefoot Shoes are designed from the start around real support — a Conforma insole matched to your arch, or a custom milled orthotic — so the shoe and the insole work as one system, not a retrofit.

Every online order is covered by our 30-day wear test: wear them, and if they're not right, return them within 30 days for a full refund of the product price. Return shipping is paid by the customer. Custom products are covered by the Absolute Fit Guarantee instead.

It's engineered around the boot, not the foot in isolation. Eight knit zones map to the places a ski boot grips — cuff, calf, ankle, arch, heel, and toe — so the sock holds its position and your foot transfers power cleanly to the edge instead of sliding inside the shell.

Thin. A precise boot fit depends on a thin, consistent layer — bulk just adds pressure points and cold spots. The Vapor is ultralight on purpose, built to all but disappear inside a Surefoot boot.

Merino regulates temperature rather than just adding heat — it keeps feet dry, warm, and odor-free across a full day. It's blended with nylon for durability and a soft, non-itchy next-to-skin feel.

All three share the merino blend, seamless toe box, ankle compression, and a women's fit. Diamond adds the diamond knit pattern; Plus adds shin padding for extra protection under the boot cuff. Peaks is the everyday Vapor.

Yes — every Vapor sock offers a women's fit. On each product page, toggle Men's / Women's to see your size.

Machine wash cool and air dry to protect the merino and the knit structure. Follow the care label on the sock for specifics.
