Okay, let me say this: if you don't own this shoe and you're a runner, what are we doing? I'm not gonna lie, the price was steep, but the shoe is amazing. I feel like I'm walking on clouds. I thought the Vomero 18 was my favorite, but I dont think so after trying these shoes. Don't think about it, get it! However, I do go up a 1/2 size in running shoes. The toe box is a little narrow, so if your foot is wide, I would recommend sizing up by a 1/2 a size.

Awesome carbon running shoes. These run slightly wider than the vaporflys, and are very comfortable for longer runs aswell as faster ones

A the huge improvement from my previous 3 pair of Zoom Fly 5's. I enjoyed the lightness and cushioning of my 5's but was diagnosed this year with osteoarthritis. Nagging pain in my left hip, knee and shoulder socket that has made running difficult, always in some pain. I was losing hope this summer. But with my new Zoom Fly 6's, most of my hip and knee pain is hardly noticeable, starting with the very first run. Unbelievable improvement for an experienced runner. I should have bought these 6 months ago despite the cost. They are noticeably lighter, faster and have a softer foot strike, better push off.. I also like the all white color option. The neon colors out there are getting old and don't go with anything else. I wear orthotics and the 6's work for them just fine.
