Which is worse, lousy cushioning or blisters?
I've got an older pair of racing flats that I love with about 125 miles on them. I'm running CIM this weekend and some people told me I will want the cushioning of a newer shoe. I ordered the same size in a newer model and they are slightly smaller. I did my test run and got a small blister on the tip of my largest toe. I don't have time to buy and test a new pair, so do I go with blisters or less cushioning?
