I started SizeSquirrel in 2016 as a way to help climbers size climbing shoes across brands and models and allow them to buy discount or used climbing shoes online confidently. Since then, the site has grown to include other features such as listing current sales, taking into account foot shapes, recommending shoes and more.

It has thousands of users and almost 10,000 shoes posted to the site, making it what I believe is the best source of crowd sourced climbing shoe information. 

If the site has helped you out or saved you a couple bucks on a shoe purchase, consider buying me a coffee! 

Thank you
