Would like your thoughts on a situation I encountered yesterday ... I have been going to the gym regularly and am pretty much back to my old routine, although less strenuous. My old gym shoes were run down, insides worn out, etc., etc. Two days ago I bought a fresh new pair of shoes thinking they'd be great. They're the same shoes I always get for the gym. I wore them two days and yesterday my knee started to ache for no reason. Not really concerning pain, but definitely more aching. Do you think it could be the new shoes? Here I thought I was doing my knee a favor with some cushy new shoes, but maybe not??? I'll experiment next week with new vs old shoes when I go back to working out. Taking a few days off from the gym.
