STEP ONĀ® bindings are ONLY compatible with STEP ONĀ® boots. Do not use either product with non-STEP ONĀ® boots or non-STEP ONĀ® bindings. Consult the size chart to ensure that you have the correct size binding for your boot size. Pairing incompatible size boots with bindings may lead to malfunction and could compromise your safety. Womenās and Menās sizing are based on different size standards. Combining menās and womenās STEP ONĀ® products will result in malfunction and could compromise your safety.
