These are the second pair I have owned. The first pair never, ever gave me any problems. I purchased them for the boa system and also being water proof. Both of these features are very important to me. One of my dogs also enjoyed these and ate one for lunch. I received the second pair and with in three days the the sole where it is glued to the very front of the shoe started pealing back. More imortantly the boa system is extremely difficult to loosen.
