Depens which style you like
I have tried most boots out there, and the klim is by far the best boot, and is the only water proof boot in the industry. They are the only one that backs the waterproofing up. I personaly like the adrenaline gtx, which does fit true to size.. This boot has got good support, it is small so you can move around, just an all around killer boot. The new gore-tex radium is great as well if you like the stiff style of boot. But i know they do run a size small, i tried them, and they were a good boot, but not what i was looking for. As far as durability, you will not find a better boot than klim. Yes your running boards will chew the sole up, but from my expierience, i can get a few years out of the klim, whereas my hmk would only go about a season if i was lucky, but it all comes down to a personl prefferance, so good luck finding the reight gear for you.
