In the last year, I've owned three pair of Asics Shoes....all size 11B. That's my size. Yes, I read the reviews that they ran narrow, but I figured these people must have just made a mistake. Nope! They didn't make a mistake. I just received my newest pair this afternoon, so the first thing I did was try one shoe on. I had an older pair of Asics on, so I slipped one off and tried on one of the new shoes. At first I thought wow, no difference. But after a few minutes I could feel that the shoe was too narrow. So, off it came and I measured the bottom against my comfy shoe. Sure enough it was more narrow. I'll be returning this pair and hopefully can find a pair of 11D in a color I like. Buyer Beware! It will apply to you! Order the same size you normally wear, but get the next wider width.
