EUC Has 150 road and treadmill miles, never in the snow. Plenty of life left for someone who wants to test a super shoe out for workouts or race day. *Every show in the fuel cell line runs .5 size small* I always am an 8 in other shoes, highly recommended that if you are a true 8.5 you skip this one as it’ll be snug. Questions, ask! If you want i can give them a good cleaning before shipping, no promises any stains come out*
