Hybrid NXT -> great version of Puma's hybrid range. NRGY beads cover the heel, while soft foam and a woven base do the rest. Not as comfortable as desert runners or rocket launchers, but still a good running shoe. The toe is narrower than usual. I always get 11.5 but it should have been 12. Puma and the hybrid sole have top of the range shoes -> small toe box - I would get a 12 when I normally get a 11.5.
