Hands Down It's Simply The Best!
As a disabled American Army combat veteran, the right shoes are my Best Friend. There is no doubt that these shoes beat any other shoe that I've ever tried, and I've tried them all. Due to injuries, etc., I am no longer a runner, but I do log more miles than just about any Ultra Runner that I know or have seen in magazines. That means many long hours on my feet.
My only negative comment is that the pair that I started using in JUN2015 only last until JUL2015. They only had about 147 miles on them and literally disintegrated. Perhaps it was a combination of body mass, hot Dallas summer roads and sidewalks, AND ESPECIALLY all of the debris that gets caught in those channels! I am a heel-strike walker and speed walker, and 2 miles out on their "final" outing, these shoes literally blew out both heels and the left one took a rock through the sole and into my foot. I've never seen any shoe come apart so quickly under what I consider gentle use. In comparison, I have a pair of Cloudsurfers that I purchased about 3 years ago. Those shoes look a bit dusty from from the road, but when you look at the soles, they look like they've hardly been used... when in fact, they have well over 900 miles on them. Yes, that's longer than the shelf life and mileage life, yet their ride is as good as it ever was and that's a testament to ON engineering.
I switched to the Cloud because of the lower offset, weight, etc. and after trying it for the first time, they were the shoes that my feet fell in love with and hurt the least from wearing.
I still walk some half marathons and Ultras, but mostly the walking is for me and my health. When I'm racing, I'm competing against my disabilities, not the clock or any other runner. I'm simply trying to regain that feeling that every runner loves when it's just you and tranquility moving through the clouds... on my Cloud.
