The tops of my feet were hurting after rides, which I thought was quite weird. A barn mate said she had the same issue until she started riding in composite stirrups. I borrowed her spare pair and to my surprise they really do seem to help.
Two questions for the COTH braintrust:
Where can I find a pair that is larger than 4.75"? Hers are a little small for me and it seems like everything out there is this one size. I found this pair of 5" at Dover, but they are pretty expensive compared to all the rest out there ($30-50 range). Plus they are out of stock.
Is there something else out there that might work? I ride in both regular irons and flex irons - both of these were causing the issue.
