This boot is much sturdier and more supportive than one would expect given its light weight.  For short hikes with a pack under 20 lb, these are great boots.  I've hiked mountains, swamps and snow with these boots and they perform admirably under all conditions.

If you're going to be humping a 30 lb pack (or you're just a naturally heavy person) I would suggest getting something sturdier (check out the Vasque Wasatch boot).
