I am a big fan of Asics shoes, I swear by their running shoes and I bought a pair of their outdoor soccer cleats that I feel are the best shoes I've ever owned.  So I am an Asics loyalist.  However, I was disappointed that these don't come in wide.  I wear a Asics 11.5e which like I mention above fit perfectly.  I bought a 12 because they didn't have wide.  But they were just too big in the toe, so I did a quick reorder and bought a different pair at 11.5 and stuffed them first full of my feet with 3-pairs of socks on and after about 2 hours of my toes going numb from being too tight in my living room I stuffed them full of the extra 2 pairs of socks to keep them stretched out and they fit great.
So bottom line if you are a wide foot guy like me go to your size and just stretch them out. Great shoes.
