Great Shoe July 6, 2016
Reviewer: Anonymous Person from Norristown, PA United States  
I have worn Apex shoes for years and am very satisfied with the fit and comfort - they are my "go to" walking shoe. The Boss Runner is comfortable but a little wide in the toe box. That is my only complaint regarding this shoe. Overall I find it to be an excellent shoe and I wear it for walking because I am under doctor's order to avoid running.
