K.A.
I just buy cheap so I don't feel too bad about having to replace them all the time. I have one son that is the killer of pants and shoes. He never outgrows stuff before destroying it. We spent money and bought him proper Levi's and those were worn out faster than the cheap ones we got from Target. That was the last time we wasted money on expensive jeans, hoping they would last longer.
We recently bought him a pair of Vans, hoping those would hold up better. At least they were on super sale, but we're going back to Payless for his next pair. It wasn't worth the extra expense.
