So comfy
Solid solid solid shoe.
The value for the money you spend is quick to be noticed. Working in a dental office, I’m on my feet a lot and all of these brands who say they were made by nurses blah blah blah are liars. These were finally the shoes that didn’t make my ankles or feet sore. They take shock absorption so smoothly, and allow me to feel supported and comfortable. Wearing them all day isn’t a chore and honestly made me realize I was less grumpy because I was much more comfortable

A great everyday companion.
Overall this is a great watch for the price. Swiss Made and the right size for a larger dial vs. others in the class. The dial color is more gray than black which was a plus for me as I was looking for a gray dial. I switched out the band for a black field band bought on Hamilton’s website. I am very happy with the results!
