I have the 2014 S-works road shoe and it is the lightest, stiffest, most comfortable bike shoe I have ever owned. Loving this experience, I purchased the same shoe in the MTB version. Both size 42, but the MTB version feels like I have a vise on the front of my feet! I set both up the same way with my BG inserts and wedges, and then backed out a wedge on each foot on the MTB shoe thinking the "last" might be a bit different and it might provide some relief. No dice. Still vices on my feet. Same effect thin summer sock or heavy winter wool sock. Any clues?????
