Customer Reviews

Comments: These were the best spikes I had ever worn until they tore during my second race in them. Just not enough structure on the inside of the foot.
From: Zach. February 16th 2015

Comments: I run D1 college XC/track...I ran 3k, 5k, and 10k in these, and they handled the distances well. I also ran in these for track workouts, and they were fine. They feel very natural on the foot, and they look great in person. My only complaint is the placement of the spikes. My teammates and I found the spike under the ball of the big toe to give blisters. Taking it out alleviated it somewhat, but not entirely. After training in them twice a week for track workouts, I got toughened up to it, but some might not like running on blisters. Otherwise, these are good for the price. Another little thing I think that could be improved is the heel of the upper. I think a stiffer material in the heel would help lock the foot down a little bit more.

Comments: The endorphins are very light comfortable spike, but they're down fall is durability. After two races the mesh has torn along the inside of the foot just in front of the arch, creating a 4 in. long hole. I am 155 lbs. and 6'1".

Comments: Initial reaction to these spikes is, I love them! They are the lightest shoes I've ever worn but don't sacrifice the protection you need. No soreness after my first race in them. I previously raced in Shay XC3's, but these felt fine. I do training in Kinvaras and Minimus 1010s and run between 30 and 45 miles a week. I got a size 14, I am 6'3" and about 160. A fantastic addition to my growing collection of shoes!
