First thing I noticed was the chemical smell, not really important since they will be on my feet, but I've never noticed it before in a Saucony. Then I wore them for a day. These are the most uncomfortable Saucony shoes I have ever worn. Much less padding than either a Hurricane, Omni 20 or even a Cohesion 13 (all Saucony shoes). Also, they squeak when you walk on a tile floor, not much of an issue for an outdoor shoe, but I wear my shoes inside as well as outside. I'll return these and replace them with a Saucony Omni 20.
