Disappointed - Bogs Classic Design A Boot - Donuts

I purchased a pair of Bogs about 4 years ago. Rarely use them but they did come in handy on the few occasions of inclement weather in New Mexico. I pulled them out this weekend because I needed to do some serious yard work after winter weather. Much to my disgust - each of them had a crack in the rubber at the top of the arch. These are a half size larger than I usually wear so they definitely are not too small. I bet these boots don't have even one mile on them and they're kept indoors in my closet. When I contacted Bogs they offered me 25% off on a new pair!! I will never buy another pair of Bogs, never. I could easily buy a cheaper knock-off brand (of which there are many), pay less and replace them as needed. I mistakenly believed that these would last for years, not 4 years....
