Mucks Boot Company Store has quite possibly the best customer service on the internet. I purchased a pair of "The Daily" shoes and chose standard free shipping. They arrived quicker than I expected but unfortunately were too small. I went online to request a return and exchange and printed a free UPS return shipping label. I also ordered a larger size pair of shoes at this time. I had the option to pay for the replacements and receive credit for the returned pair after they were received back or wait until the returned pair was received back and the replacement pair would then be shipped. I chose to pay again. The new pair was shipped immediately 2nd air at no additional charge. They fit perfectly and I really like them. I received credit for the returned pair 2 days after receiving the replacement pair. I very highly recommend Muck Boot Company if you are looking for waterproof boots or shoes for yard work
