Hybrid NXT -> great version of Puma's Hybrid range Hybrid NRGY beads wrap the heel while soft foam and 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.
