They both seem to be right on. There seems to be a big gap between 12s and 13s in the tours. Have owned a pair of 12s for a year now and they have always felt a little snug. Ordered a new pair of 13s and they were huge...couldn't even come close to fitting. If you wear a 12 in street shoes, i'd go with 12s in the tours. By the way, as an owner of both and this is my personal opinion, buy the tours. I will never own a pair of Dexters again. Always fell apart. And as a pro shop operator for many years, spent a lot of that time trying to glue customers' dexters back together. Just my opinion. Have never had a problem with my dynorooz. Take it for what it's worth. Good luck!
