My cobbler, Jeff at Cobblestone Shoe Repair in Creve Coeur MO told me, very delicately I might add, that AE's are prone to that flex in front of the heel, especially with larger men like me (235Lbs), and that if it gets really pronounced as the shoe wears, the leading edge of the heel can start wearing, not just the trailing edge where it normally strikes the pavement. He seems to be right, I have a tired pair of AE McAllisters that the heel is wearing funny, and the wear pattern on the sole is moving farther and farther back toward the heel...
