I guess I'll be the grouch... :^)
$150US (~$200CAD?) is a bit rich for a shoe that appears it may not last more than a couple of months. I used to get sick of my 5.10s lasting ~3/4 of a season but that would appear to be as good as it gets for me. I tried the Shimano's a couple years back and only OK fit (a personal thing), I could live with the limited grip but the sole ground to bits in a few months and I didnt feel worth buying another pair. I got a very nice pair of brand new Ride Concepts Powerlines for this season and havent been impressed either. its a (really) nice shoe, the grip is good enough but the soles are shredded to bits and its been a down year for me for riding time.
I was going to try a pair of the Specialized ones per AJ's articles but Jenson doesnt ship S products to Canada so I just got a new pair of the 5.10 Impact Pros and I think I'll leave it at that. I know what I'm getting, the grip is as good as it gets from what I've read, and I know what to expect for wear.
