This shoe is really light but it unfortunately is not built for my feet. After I ran with it a couple of times my left ankle hurt and did some research. Turns out I am a "under pronator" and this shoe is more for normal and over pronator. I never knew about this stuff until after I bought the shoes so make sure you do some research before you buy running shoes!

What I can tell you is that the shock absorption on these are amazing. My knees are definitely very happy!
