I always try to purchase a wide sneaker to accommodate extra arch support.  I inserted the support and was pleasantly surprised there was enough room for a heavyweight sock as well.  I was off on a 5 mile walk to see how they performed.  I was so pleased with the cushion, fit, breath-ability and foot comfort I immediately ordered a second pair.  Very happy I found these sneakers.  Well constructed and after several wears - no blisters or wear scars on my feet.
