Step Swap
The community for mismatched feet — find your SoleMate and swap shoes fairly.
Overview
Step Swap is a mobile-first marketplace for people whose left and right feet need different sizes — or who want to trade same-size shoes for new colors. Guests can search by size and preview anonymized matches before signing in; members chat in real time, pay a per-swap service fee via Stripe, and ship with prepaid labels on both legs. One React codebase powers the web app at stepswap.sk (plus EU ccTLDs) and a native Android app.
Tech Stack
The Challenge
People with differently sized feet — often due to medical conditions — routinely buy two pairs and discard half of each. Single-foot wearers face the same waste. There was no trusted, structured way to find a complementary SoleMate, agree on a swap, and handle cross-border shipping and payment safely between strangers.
Our Approach
We built a single React + Supabase + Capacitor codebase with Deno edge functions for checkout, label creation, and carrier webhooks. A server-side dispatcher routes each shipment to Packeta (SK/CZ/HU/RO/PL) or Sendcloud (AT/DE). The product ships in seven languages with localized legal pages, a guest conversion funnel (size search → anonymized preview → sign-in), public delivery-fee pages, and SEO static mirrors for FAQ and community content.
The Result
Step Swap is live at stepswap.sk across EU country domains with the guest funnel, production payments, and multi-country shipping in daily use. The Android app is on Google Play Internal testing. Sentry crash reporting and consent-gated analytics keep quality and privacy in check on web and mobile.
