Customer Reviews

Comments: I have been running in the first trail glove for about 7 months. It is an excellent, albeit, unforgiving shoe. I wanted to try this newer version with more cushioning and more agressive tread. In the first mile, I felt great. The next half mile, I started feeling hotspots in my right foot in several places. I took the shoe off, and adjusted the laces. It did not help for long. I then ran further, and started feeling my left foot developing hotspots. I cut my run short and ran home. After only five miles in these shoes, I delveoped five blisters on my left foot near the arch and balls of my feet, three on my right side. Each blister had the little cross from the nubs on the sole imprinted in them. I took them back the next day.
