I've had these shoes for about a month now and couldn't be happier with them. I use them primarily for dog agility (which involves running, sprinting and sharp turns on various surfaces) and hiking. The fit is normal for a sneaker, both size and width. Although slightly heavier than a normal running shoe, they are very comfortable and the other features more than make up for the extra weight. The rubber cleat-like bottom gives fantastic traction, even in wet grass. The waterproofing is very effective, I've run through tall wet grass and stepped in a rather large puddle, and not a drop of water has gotten through to my socks.
My only complaint, and it's a very minor one, is that I wish they came in other color combinations, I'm not really fond of lime green. But performance-wise, these shoes are great. Heavier than a regular running shoe but lighter than a regular hiking boot, with the traction and waterproofing of a hiking boot and the low profile and fit of a running shoe.
