Technology Glossary

Saucony shoes come with many different features, focusing towards different elements of the running gait and/or varying foot types. With so many differing features it can sometimes become quite overwhelming so we've created a Saucony footwear Glossary to help you understand the features within our wide range of waling, running and performance shoes.
