I run barefoot during the spring & summer but despite my best efforts I just can't do it in the winter (it's not really the cold that's the problem, it's when it's wet and cold that I battle). Last winter I just stopped altogether, but I don't want to do that this year, so I want some running shoes that are really light. I've tried Vibram 5 Fingers and I didn't like them - I'm considering Asics Gel DS Sky Speed at the moment. Any other suggestions/insights?
