I had been searching and searching in stores for the Asics gel TRAINING (NOT running) sneaker with no success.  I don't usually like to order shoes online b/c I have a tough foot to fit but in desperation, I took a chance and ordered the shoe on Amazon.  I was releived when the shoe came and it actually fit!  I ordered a 1/2 size larger then my normal size b/c "wide width" wasn't available and some of the other reviews indicated that this shoe was sized small.  Not having the opportunity to try on my "normal" shoe size, I can't say which would size work better.  This shoe is a little larger then I think it should be and I find my heel slipping out of it after doing certain exercises.  I do not know if this is a problem w/ the shoe size or the laces- they seem to not stay tightly tied.  I might try getting different laces for it to see if that helps.  Overall, this is a good shoe. I use it for aerobics, Zumba, various strength training classes, elliptical and bike, and bootcamp activities.  Besides the issue w/ the shoes slipping off my foot a little, the only other issue I have is that these shoes are a little slippery on hardwood floor but its not unbearable.  Overall, good shoe, good price, would recommend.
