Customer Reviews

Comments: This is the best spike I have ever owned. Much better than the nike victories in my opinion. I use these for the 200m-1600m, and they are perfect for each of those events, and they are so light! You won't be disappointed in these. I love them!
From: James, Patton, Kimberly, Alabama, US

Comments: Very great feeling shoe, setting PR's every race so far, conforms to your foot nicely, and super light! I would definitely recommend these to anyone who wants to shave time and run well.
From: Noah, USA

Comments: By far the best 800/400 spike i've ever used. I used to run the 800 in Maxcat III's because I liked the stiffness of its plate but the weight was a con. I then reverted to my victories but didn't like its spike plate as it wasn't stiff enough for me. my dilemma was solved with the endorphin three spikes. They weigh almost if not the same as the victories but have the stiffness very similar to that of the Maxcat. They are the perfect combo of weight and stiffness and put you right on your toes the entire race- an overall amazing spike.

Comments: Feels great like there is no heel to keep you on your toes. I think this rivals the Victory.
From: Derek, Placentia, CA, USA

Comments: Great energy return, the feel is perfect. Saucony outdid themselves on this bad boy.
