I usually buy Reeboks, but couldn't find the right shoe this time.  Settled for these with the following observations:  this 4E is not as wide as Reebok 4E;  length of size 10 equal to 91/2 in Reebok;  look OK, but not as good quality as Reebok.  So I'd say buy up one half size.  But if you need a 4E wide width, buy a different shoe.
