I’m constantly amazed by the information I can find in the TR forum, but haven’t been able to find anything on insole wear patterns, and whether any useful information can be drawn from the wear itself, good or bad.
Shoes are MX237s in wide (yeh, I’m one of those SPD on the road bike folks). Cleat position is a touch behind the ball of my foot. Insoles are SQlab 215 medium support, are 13 months old, and have about 15,000 km or so on them (99% road miles). The insole material is pretty compressed/worn under the ball of the foot and under the big toe, to the point where I’m thinking replacement might be in order. Debating whether to stay with these, or try a different brand, too (Specialized perhaps).
Does the wear line up with what you’re seeing on your insoles? Is it normal to see that much compression under the ball and big toe? Am I just weird for asking this in the first place?
