I have only been able to wear once.  4E width was more like 2E.  Very tight and too painful to wear second day.  Was very happy with the slip resistance.  Seemed well made (only wore once though).  Invested in shoe stretchers, so hopefully will fit better.  I notice all shoes are narrower every time I buy a new pair.  Not just this brand.  Maybe i will owe the shoe stretcher a 5 star.
