“Great concept, however...”

“Conceptually the product is a great idea, e.g. lets water in/out & keeps out sand, etc. It also looks great and has great name recognition (Teva). However, the top-most strap is prohibitive in that it does not stretch wide enough, and makes it difficult to put the shoe on and take off! Also, once the shoe is on, the part above your toes is very hard. After several hours of wear, you end up with blisters on top of your toes. I never imagined I would have this kind of experience form a pair of Tevas!”
