These undies are comfy and don't ride up. I doubt the anti bacterial lining makes that much of a difference. They didn't dry as fast as I'd hoped, they still took about 4 hours hanging off my pack to become very very dry, but I am still happy with fit and comfort and all that.
I bought this shoe for running on the road and for some trail running, this shoe is great, it's lightweight and fits my foot well. However, this shoe doesn't provide much support for the ankle. A great shoe if you just want a lightweight running shoe, but if you need some support, I'd say keep looking.
