I own three pair of these. 12 is too small; 13 is too big! I had no choice but to buy 13's. Why not try a 12.5 size for a change? They're sure to last a lot longer than mine have with my foot sliding around in them constantly (even with orthotic inserts replacing the removable "comfort insoles.") What I'd really be pleased with is a 12.5 EEE version of these otherwise perfect shoes. G.
