I spent time reviewing a number of walking shoes. I wanted ones that were comfortable yet able to be laced up snug. I also didn't want ones that look too nerdy which I've found walking shoes have a tendency to look like (especially the ones using Velcro instead of laces). I came upon the Avia A339M and immediately noticed they looked more like cross-training athletic shoes. They also had 4 stars with good comments, a great price compared to a majority of the others and qualified for 2 day prime shipping. Well, after receiving these shoes I actually like them more than any athletic / walking shoe I've purchased in a number of years. They are extremely comfortable yet are able to laced up tight for a snug fit. With respect to size, I ordered my normal size of 10.5 (even though I thought of ordering a 1/2 size bigger) but in the wide version as I have found my feet require more room on the sides as I get older. I was a little concerned after reading the other comments (i.e. 'order one size larger', etc.) but after wearing them a few times now I've found the length and width to be perfect! I highly recommend these walking shoes!
