I haven't run in the Moab area yet. I know they have quite a few good races over there. I wonder how the weather was for the Moab race, huge storm in my area that I was out in for 10 hours.
Don't worry about your Altra shoes, I have quite a collection myself. Maybe we can all join forces and have them make a more minimal shoe.
I saw pictures, and there was a lot of snow on the ground. One of my friends had a PR, though. I went running this morning, and for some reason accidentally checked the Moab temperature on my iPhone. At 8:00 this morning, it was 3F there. That's got to be pretty unusual! I've done both of the road half-marathons in Moab (The Canyonlands in March, and The Other Half in October) twice each, and they're great races. Very well organized, and lots of fun. I would like to do the trail half-marathon someday. I would have done it this year, but one of the bands I play in had a gig that night, and I wouldn't have made it back in time.
As far as the Altras go, I'm not worried about them (other than a generalized nagging worry that I have too many pairs of running shoes!). I view barefooting AND shoes both as tools. I have definitely noticed an improvement in my form, comfort, and even speed since I started messing around with minimalist shoes last year and barefooted running earlier this year.
