How can we help?

We take the shoe model's declared lifespan — the kilometres it's built to hold its cushioning, usually 640–960 km — and subtract the logged mileage for that specific pair, read from the seller's connected Strava. The result is shown as a percentage: a shoe built for 800 km with 200 km run reads 75% life remaining.

No. The mileage is pulled from the seller's Strava, counting only activities tagged to that pair of shoes. Sellers can't edit the figure by hand — which is the whole point: the number on the listing is the distance the shoe actually ran.

If there's no verifiable mileage, the listing is marked Unverified and shown without a % life figure, so buyers can tell it apart from a verified pair. We'd rather show nothing than guess.

Connect from Your account → Connections and approve read-only access to your activity list — we never post to your account and never see your login. Disconnect any time from the same screen; we also call Strava's deauthorization API to revoke the tokens. You can additionally revoke access at strava.com/settings/apps.

We request read, profile:read_all and activity:read (and activity:read_all only if you opt in to private-activity verification). Only the “verified runner” badge and % life are public — numeric mileage and activity detail stay visible to you alone. We cache derived verification aggregates for up to seven days and never store raw activity streams. On disconnect, or on request, we delete your Strava tokens and related verification data.

If a 403 “limit of connected athletes exceeded” appears, our Strava app cap has been reached — try again later. If the badge doesn't update after connecting, refresh or retry in 1–2 minutes while our cache updates. Still stuck? Email hello@itisnorma.com with your NORMA email and Strava athlete id.

When you pay, we hold your payment rather than send it straight to the seller. Once the shoes arrive and match the listing, you confirm receipt — and the seller is paid. If you don't confirm, the payment releases automatically: 3 days after delivery for a posted order, or 14 days for an in-person handover — unless you've reported an issue.

Payouts run through Stripe to your linked bank account after the buyer confirms receipt. NORMA takes a 5% platform fee on the sale price — there are no listing fees and no subscription to sell. Track the status of every sale on your payouts page.

Don't confirm receipt. Report the issue from the order (or your chat thread) before the confirmation window closes — 3 days after delivery for a posted order, 14 days for an in-person handover — and include photos if you can. Because your payment is still held, nothing has been released to the seller — we'll review and sort a return or refund.

If the seller hasn't shipped yet, request a refund from your order (tap the menu in the chat thread and choose Request refund). Once the seller has shipped, refunds are handled by our support team. See the full refund policy.

Once approved, refunds typically appear on your card within 5–10 business days, depending on your bank.

Browse on Browse and filter by size, condition, brand and price. Check seller profiles and Strava badges for credibility, and use Messages to ask questions before you commit. Pay securely at checkout and your payment stays protected until you confirm the shoes.

Choose Sell your pair, pick the model, and connect Strava so we can read the mileage. Add clear photos — outsole, midsole, insole, size tag and any defects — a short honest description of the wear, and a price. The % life figure is filled in for you.

On listings marked Open to offers, yes — send a figure from the listing and the seller can accept, decline or counter. Everything stays inside NORMA so your payment protection applies.

Confirm the size system (US/UK/EU/CM) on the listing and ask the seller for the size-tag photo. Consider brand-specific fit — message the seller about toe-box width and heel fit. For orthotics or thick socks, consider sizing up 0.5 if you're on the edge.

New / Like New — tried on only, outsole pristine. Lightly Used — minimal outsole wear, no midsole creasing. Used — noticeable outsole wear, mild midsole compression, minor scuffs. Heavily Used — significant wear and cosmetic defects; price and disclose accurately. Always include photos of the outsole, midsole, insole, size tag and any defects.

Sellers post with a tracked service and add the tracking number, so you can follow the parcel to your door. The delivery cost is shown on the listing before you pay.

No replicas or counterfeit items, and listings must use original photos taken by the seller. Only list items you own and have in your possession, and be honest about condition, mileage and any defects.

Keep communication respectful and on-topic in Messages, so you have a record of agreements. Spam, harassment and abusive messages are prohibited, and you shouldn't share personal contact info publicly.

If you arrange a local handover, meet in public places during daylight, bring a friend if you'd rather not go alone, and inspect the shoes before completing anything.

For a problem with an order or listing, use the report a problem form and our team will look into it. For anything else — including suspicious activity — contact us. Violations of the community guidelines may lead to listing removal or account restrictions.

Rentals let you try shoes for a race or training block without buying. Agree the rental duration, fee and deposit up front, and check the shoes when they arrive.

Take photos of the shoes when you receive them, and return them in the same condition — allowing for the agreed use — by the date you agreed.

State your rental terms clearly on the listing (duration, fee, deposit), document the shoe condition with photos before handoff, and consider a security deposit against damage.

Sign-in is one-time-code based for security — we email you a code each time. If the email doesn't arrive, check your spam folder and retry from the login prompt.

The profile data you provide (email, name, optional location); if you connect Strava, your athlete id and access/refresh tokens (encrypted) plus derived verification aggregates. We don't store raw Strava activity streams. Full detail is in our privacy policy.

Manage your details under Your account → Profile. Disconnect Strava there to revoke its tokens. To close your account and erase your data, use Delete account on the same screen — the privacy policy covers what we keep and for how long.

Read the full Terms & Conditions and Privacy Policy — the latter covers how we collect, use and protect your data, and your rights under UK GDPR.

Prohibited items: counterfeit/replica shoes and stolen goods are banned. Data privacy: we minimise what we collect and you can request deletion. Local laws: comply with your local tax and consumer regulations when selling.
