I bought a pair of the Land's End mesh sneakers last fall after reading about them here. I wore them around the house for a day or so and took them back to Sears the next day! They have absolutely no arch support. I didn't get any blisters from them, but my feet were not happy. I ended up buying a pair of Nike sport sandals (they might be called Deschutz or something to that effect) and I absolutely love them. I can wear them all day and my feet feel great. They have the Nike sole with waterproof sandal straps that can be worn in water or on land. I even wore them in my son's little pool in the back yard and then walked around to see how fast they would dry or if they were uncomfortable when wet. They were a little slippery for a minute or two, then went back to being great. I think they will be perfect for Kali!! The only bad thing I have found is the little ridges on the insole. They can colllect dirt from puddles you walk through and look pretty ugly. they are easy to clean once you take them off. I found them at Nordstrom's, but I think they can be found lots of other places. Good Luck! ---H
