"The shoe was initially fine. I did not encounter the squeaking others mentioned but after less than 3 months of wear, the sole began separating from the upper at the toes of both shoes. This allows dirt and crud to get in there and get carried indoors with you. I also had a real problem with mold in the shoe that I have never had before."

"I have been buying NB shoes for years but this shoe is horrible! The sole squeaks and it is not only irritating but very embarrasing as well....."

"856 has been my shoe ever since I got custom orthopedic inserts. This 857 has seams that cause my little toe to have blisters. I had my shoe stretched, the orthotic insert modified and added padding to try to get the 857s to work...but I just hate walking in them due to the pain...I am done with them."

"I've been using the NB 850 series for many years. For some reason the new 857 has a newly designed insole that has 4 raised rectangles in the arch area of the insole. Not surprisingly, these caused some pretty bad blisters on my first long walk with them. I can't recommend the 857 with the new design insole."

"Have worn the high end NB for 12 years after Dr. recommended. Three pairs per year. Not one problem until the 857 came out. Less comfortable and they squeak so loudly when I walk that it's embarrassing. Tried everything to make them quite. No luck."
