I've switched to a new pair of shoes and I almost have cleat position dialed except some issues with my left hamstring. There's no pain but rather it feels like I'm overusing my left hamstring when riding. Does anyone have an experience with this or know how I may correct thru cleat positioning (cleat fore/aft)? Everything else feels good so I'm reluctant to mess with anything else (eg: saddle height, right shoe cleat position, etc.).

Thanks!

Hamstrings are overused when your seat is too low.
