After readinbg a few posts on this forum I thought I would give you guys a question. Im 70 years old, 2 repoalcement knees, been riding seriously on and off for near 55 years. Since my last knee replacement I have developed arthritis in my left foot big tow. its right abouve the ball of my foot. I ride 3 bikes, road bike, mountain bike and a Specialized Sirrus 6.0 "fitness bike" I have less post ride pain on my flat pedal mountain bike, road bike is worse and sometimes very painful. Now my question. I use Shimano SPD on my road bike. What do you think of my placing my cleats as far back on my shoe as possible meaning more of my instep is on the pedal than ball of my foot, anyone tried this? Im not training for the Grand Tours, did that in the '60's lol!!! Shoes are Fizik R1 infinito, super stiff, for me anyway.......
