i'm looking for some advice from those of you that own a pair of Alden Indy boots. I know nothing of the Tru Balance last and was told by customer service at TSM that this last is true to size. I measure a 9D on a Brannock device and also wear a 9D on the Hampton last. However, I always wear a size 10D for tennis shoes. Should I just go with a 9D or a 9.5D?
