Why We Built SneakTools

The Problem We Solve

If you've ever ordered a Nike in your size and had to return it because it fit nothing like your Adidas — you understand the problem. Sneaker sizing is inconsistent across brands, across models within the same brand, and across men's and women's sizing systems.

At the same time, the same pair of shoes can cost $40–$80 more on GOAT than on eBay on the same day. Most buyers don't know this because they check one platform and buy.

SneakTools exists to fix both problems with free tools anyone can use without creating an account.

What We Build

Our tools are built around one goal: helping you buy the right shoe at the right price the first time.

• Size calculators — Nike, Adidas, Yeezy, Jordan, Dunk, Hoka, ON Running, and more
• Size conversion charts — US, EU, UK, CM across men's and women's
• Women's to men's size converter — for shopping on resale platforms
• Price comparison links — GOAT, StockX, and eBay side by side
• Resale guides — which shoes are worth buying and which to avoid
• Buying guides — honest comparisons like Hoka vs ON Running

How We Work

Everything on SneakTools is free. We earn a small commission through affiliate links when you click through and make a purchase — at no extra cost to you. This is how we keep the lights on and the tools free.

We only recommend products we'd actually buy. We don't accept paid placements or sponsored rankings. Our comparison tables reflect real pricing and real differences — not advertising relationships.

Who's Behind This

SneakTools was built by a team of sneaker buyers who got tired of sizing mistakes and platform price gouging. We're based in Los Angeles and have been in and around the sneaker world for years.

We update our size guides regularly as brands release new models. Our resale cheat sheet is updated monthly with current market values.
