Biggest disappointment was discovering that the sides of the tongue were stitched to the sides of the shoe opening all the way up.  Even though there is some elastic webbing in there, it makes it VERy difficult to get the shoe on if you have even slightly wide feet.  Once I managed to stuff my Fred Flintsone like foot through the opening they were a great fit, but they are just way more effort to get on than I was looking for.  Change that opening and I'd automatically make them 5 stars because of price, comfort, light weight, color selections etc
