CUSTOMER RATINGS & REVIEWS
Terrible, tried calling numerous times, emailed numerous times and no answer at all. The item I received isn’t right or what I ordered, however I was forced to use them for my meet bc I had no other choice and you guys never got back for week before then. Thanks.
I am a sprinter who runs anywhere between the 100-400 and I was very impressed the moment I put these on. They are very comfortable and give you a fast feel when running. The rigid full-length spike plate gives you a good reactive feel and is extremely lightweight. The BOA lacing system allows you to adjust the fit to your liking. Compared to other spikes, this lacing system wraps more around the foot to create a more secure and snug fit that takes only seconds to tighten. As a sprinter, I love my spikes to feel snug like a sock and this is exactly how they fit. It does run a tad longer and wider than it has in the past. A plus is the sleek design!
