I have size 13 feet also….what kind of footwear are you wearing? I’ve never had a problem wearing hiking boots/work boots while kicking. But after its winter nap, I have tried kicking it with tennis shoes on……nope…..won’t do that anymore. Also I am kicking 158/157 psi and have no issues. I do run cut down rear fenders, but when I put my fulls back on, I still do not have an issue with catching my calve on the plastics. Oem starter here
