I just bought a set of Shimano RC5 road shoes, and I could only wear them for about 60 seconds on the trainer before the stabbing pain in my Achilles tendon was too much.
The shoe fits fine otherwise, and--unlike a lot of shoes--doesn't bang into my ankle bone, but the back of the shoe seems to come up quite high, and is rubbing against and/or digging into (depending on where in my pedal stroke) the back of my tendon. I was curious, so I pulled out a very old, very cheap Shimano shoe from 12-15 years ago (left), and it seems like it MIGHT be a tiny bit shorter in the back, but it definitely has about a half an inch of pliable padding where the RC5 has stiff shoe.
It looks like I'll have to return these, but does anyone have any suggestions for a lower-heeled road shoe?
