To anyone who has ever run track, just imagine what it feels like to wear a pair of properly fit mid distance track spikes on the track and this is what the Bullet is on streets and regular surfaces. It's light and flexible and just feels good but it fits a bit snug and might be a little tough to wear for a while when you get them but they're absolutely worth the money if you get them in the right size. I happened to get these off Amazon on a guess about size and I was a half size too small on it which wasn't uncomfortable but just maybe a little too snug for extended use for me personally. Also, VERY IMPORTANT! They will make your feet look smaller by a sizable amount as I'm 6'4'' and have size 10's which sucks beyond description but I can get away with some shoes in 11 and look proportionate. Since I read that these fit true to size, I got them in 10.5 and I look like I have the feet of a 7 year old girl with them. Regardless, the shoe is ill
