...don’t wear them any more.
I had a pair of Reebok DMX 6 that I wore into the ground. The soles were barely on any more. You know those air pockets? They were worn through and any time it rained my shoes would squeak and squish for a day or two after it stopped.
Anyways, these shoes were super comfortable, but I found out later they were ruining my gait, and I had poor pronation in my feet because the outside of the sole had worn through but the inside near my arch was relatively still there. This led to odd rolling problems in my step and pain caused thereof.
Don’t hold on to them too long!
