My husband has the hardest time finding a comfortable exercising sneaker..well, here it is.  this is third pair of the same color, same model so it must be the right one!!  Hard to find a WW.  Believe they suggest a half size larger and that works perfect.
UPDATE:  Thought I was buying same running shoe 8/16 but came with velcro on heel.  After reading other reviews that had same problem with the velcro...thanks to gentleman's review....found you need to order 521MX115.  Wish Amazon carried that style.  Returned shoes and called Apex to order correct one. Yesterday hubby received right shoes exactly as the other 3 pair he has worn out over last decade. Only difference is "Apex" on back of heel.  The Rhino X which I originally ordered thru Amazon is now Boss Runners 522M and has the velcro.  Apex sent catalog along with shoes with the correct picture showing the velcro.
