These shoes have an amazing outsole (if you are a midfoot striker) but the upper is a complete failure. If you are a clydesdale with wide feet, forget about this shoe. The toebox is nice, but the rest of the upper literally has no material to cover the rest of your foot. If you normally wear a 4E width like I do, the outsole will accomodate your foot due to its unique shape, but you may find yourself spilling over the sides a bit.<br /><br />The outsole also may not be good if you are a heavy heel striker while running and this is certainly not a shoe you want to be standing around in. Even though I am big, my feet and foot motion are about as neutral as can be. While standing in this shoe, it tends to turn out your ankles. I guess because of the heel contour and the zero-drop platform, you tend to fall back and can easily roll your ankles just standing around. I have a history of ankle sprains and this definitely doesn't lend me any peace of mind. The only way this shoe is comfortable is in stride. It literally feels like running on a cloud or like I have a pair of tits strapped to my feet.<br /><br />The upper is really the biggest disappointment. The metatarsal area is really constrictive. It cuts into you in stride, though the material isn't very substantial so as to cause too much pain. There is just not enough depth to comfortably cover and secure the foot. I don't know if it's because this is a size 15 shoe, but it seems like they didn't keep the same aspect ratio on the upper. It looks like it has the same depth as the small sizes, and this is a huge problem because foot volume goes up by much more the larger the shoe size becomes. I have included some pictures so that you can see how ridiculous this is. I have boat shoes that secure my foot better than these do. The laces are also terrible. When you pull them tight they stretch and get thin like rubber bands. You can feel every lace through the flimsy tongue, and they feel terrible.
