The sole on my Nike Roshes Runs that I purchased from Zappos has worn out in the back almost completely and I was wondering if I can send the shoe back and get a new pair, sole, or a discount of some kind.The sole on my Nike Roshes Runs that I purchased from Zappos has worn out in the back almost completely and I was wondering if I can send the shoe back and get a new pair, sole, or a discount of some kind.

No. Unless there was a awesome warranty for this....its natural wear and tear. Any repair or replacements are coming out of your pocket. If you look on the receipt it tells u about the return policy.....However they do not owe you because you got your use out of them. Not everything will last.
