Trail running shoes might help, at the expense of less comfort. Also Yaktrax Ice Grippers could be helpful. I'm gonna be running into the same problem since I live in North Dakota.

Nice! I didn't realize there was a pull ups app too! Just downloaded it. Now if I can only figure out where to do pullups without a gym membership... Also, I find it kinda odd that the app expects you to be able to do 9 right off the bat.. might just be me though since I've always had a bit of a weaker back.
