These are probably the lightest pair of shoes I've ever owned. They're definitely lighter than most of the racing flats I used throughout high school, and college. They're fairly similar to racing flats, and there's not a whole lot to them. I can't recommend them for every runner for every day use. You're feet are going to take a beating if you're not used to minimalist shoes. They're a great minimalist shoe, but have almost no cushioning of any kind. They feel great to run in! I like minimalist shoes because they seem to give you a better response for the surface you're running on, and I don't like extra cushioning in the heel. I've always been a forefoot striker, so I didn't have to adjust to minimalist running. That has never been a problem for me, but I could see problems for someone trying a minimalist style shoe for the first time. They run a bit larger than other shoes I've tried, and don't fit too snug (good for me, having a short wide foot). These shoes really do give you that barefoot running sort of feeling.

My only complaint is that the back of my foot tends to slip out of the shoe in wet running conditions (snow/rain). They're also a bit slippery in rain. I've also had a pair of Brooks Pure series shoes with this problem. I probably shouldn't have sized up by 1/2 size. Generally minimalist shoes tend to run small, but these seem to run true to size... or even a bit big.
