these shoes are great, with my type of work I am always surrounded by water so to not have to worry about my shoes getting all wet is great. I love how easy they are to slip on and the comfort is amazing. Having said all that there are some things that I would change; there are times where I almost slip on a wet and slick floor so extending the grip on the shoe to cause less grip would be great. Another thing that I have noticed with these particular style of shoe is that you can't tie the shoe very tight or it starts to feel uncomfortable on the top and side of the shoe, and because you cant tighten the shoe to much it makes the shoe a little loose. If the shoe could have a support on the top to distribute the tension so you don't feel any pain or discomfort when you tighten the shoes that would really help. These were the only things that I found that bothered me a little, but other than that its a great product.
