When they say these shoes will set new PRs, that's no joke! My first race in these shoes I set a new 5k personal record. When I first put them on they felt very different, but after a couple runs its no big deal. These shoes are ridiculously light compared to other shoes I've ran in over the years, an it's noticeable while running. The faster you run the better an more at home these shoes feel! I just only wish my fitness was as fast as the shoes. I'm very pleased with this purchase! I will most likely keep these as my race day shoes an buy another pair of Saucony shoes as everyday trainers.

Decided to try these after experimenting with different manufacturers' foam cushioned shoes, and one other pair of carbon plate shoes. It's still very early but so far, it's a quite good experience. The faster I go, the more springy they feel. I'm trying to pay attention to what foot strike and stride length works best to avoid overworking my plantar fascia, achilles, and calves.....these shoes do make me want to shift more toward the forefoot. By coincidence, I have just switched all my training to metric, so the pace charts on the bottom of the box in min/km as well as min/mile are very useful! Overall an excellent shoe for me.

Great racing shoe. Super light-weight, yet great cushion for longer distances. The speed-roll design is amazing for racing. Just did a hard 8 mile run in them and I didn't have any foot pain. They do feel like they are propelling you forward which made it easier to maintain a faster tempo with minimal effort.
