I got a pair of these after finding myself disappointed with the Wildhorse model, which has a dirt bike tread that is dreadful and downright dangerous on anything other than dry conditions. That shoe fails with flat wet rocks and stone, and has a midsole that either has no rock plate or a weak one. Also, the "collar on the horse is pretty worthless because it is not snug to the ankle. I am very pleased I made the switch to the Kiger (and hat's off to Nike for making it easy to make the swap -- great service). This shoe fits well, true to size, snug heel, plenty of (but nor too much) wiggle room in the toe box. I swapped out the stock insole for a happy feet one because I have a weak arch. Just enough room up front to accommodate movement particularly downhill. Zero "toe-crashes". It has a very well thought out tread pattern that helps uphill and down. Ihe midsole rock plate works well, I found, even on wet flat stone speckled with dirt, leaves, or sand. The ride is perfect: Cushioned and protected while still responsive enough so that one can "feel" the terrain over different areas of the feet and react. My only minor grope: the shoe has very little lateral sole to wrap the outer parts of the foot, which often come into contact with the stuff of trail running: rocks, roots, stones, concrete patches on bridges, etc. Correcting this would add very little weight and provide a safer and more confident run. I have seen complaints about the shoes performance in wet conditions, and in my opinion those complaints are misplaced. This is a shoe for wet TRAIL running. It needs to have both knobby tread and a flat area (the midsole) for navigating wet rocks and the like.The very presence of knobby treads on any shoe is going to compromise traction on wet stone. Period. That is simple physics. The tread pattern simply cannot provide complete traction because essentially half the bottom of the forefoot and heel area grip has been cut out to make tread tha work in dirt and mud. But there is a midsole that is optimally designed and works when used properly.. Runners mus concentrate on the midsole when treading on stone and concrete areas that appear in the trails. The trail is an obstacle course. This shoe is ready for it if the runner is. Nike could easily make a shoe that is virtually 100% slip proof for running on wet stone. But then there would be no tread to run in mud and sand and muck and simple dirt. Hope this review helps someone out there. Peace & happy trails. The Wildhorse should never be used in wet conditions. it has no flat "wet" section at all, so it is like riding a motocross bike with knobby tires across uneven wet stones. if the rider falls, it is rider error. I did fall, and it was my own damned fault. Lesson learned. Get these shoes. You won't be disappointed in them (but you might realize that you have some learning to do still...)

This shoe is built right. It is tight enough around the top of the opening that rocks do not often get into the shoe. I hike in the AZ desert mostly, so that is very important to me. It is also well vented, so it stays reasonably cool. Well cushioned, too.

Amazing trail running shoes. Only complaint here is that the Terra Kiger 5 was slightly better in that the tab on the heel helped me put the shoes on, whereas this doesn't help at all. The lip still gets stuffed in there because the tab doesn't help at all.
