Not wanting to mess with a good thing, Asics showed good sense and didn't change too much from its previous version. The most notable differences are the brighter colors (picante & sun), the less integrated (and more comfortable) tongue, and a more complex tread that seems to work just as well, if not better than, the previous pattern.

If it has one major drawback, it could be that it's just not beefy enough to hold up to big big miles week after week in the backcountry. In many ways, it's a racing flat for the trail, and if you feel you're going to be pounding out 80 - 90 mile weeks up and over mountain passes you might want to look for something with a bit more substance. But, if your goals are a tad more modest, the Gel-Trail Attack 4 is a hard shoe to beat.
