Size Guide

Feet come first

Why do people love their KEEN sandals, shoes, and boots? It's simple. They make their feet happy.

Secure Heel

Every KEEN starts with a secure heel fit to ground every step with stability.

Room for your toes

When toes have space to splay out, it supports posture, balance, and propulsion through the gait cycle.

Built for feet

We build every shoe from the ground up using an anatomical last (aka foot form) and fine-tune the arch support and cushioning.
