These shoes are amazing! I work in surgery and usually treat for more than 6 hours at a time, all the time standing up. They have amazing support and I never feel like my feet hurt at the end of the day. I bought my first pair about 10 years ago and you can see the wear and tear in the pictures. They are still very comfortable and have loosened to fit my foot perfectly. The only reason I bought new ones was because the inside of the sole was worn to plastic which is a bit painful but that may have only happened last year. They've been through it all, rain, snow and bloodbaths. They are also very easy to clean, which is a must in surgery. I would definitely recommend this shoe to anyone who stands for long hours and wants something that lasts! They are definitely heavy and it took me about a week to get used to them, but having been wearing them every day for many years now, I find it weird not to wear these shoes.
