Thank you! This info is very helpful! And I am going to look at the Atmos again after reading your description. Actually the wide toes with narrow heels is a more common shape than you might expect. For years, New Balance offered shoes made on the SL-2 last which is exactly this shape, but then they stopped making most of them, and in the walking shoes, changed it to wide heels. Sigh. I'll let you know how the Ultrafly5 fits. Thanks again.
