Bought these on Amazon lightening deal. I am a size 8/8. Diagram a little tricky to read, but all the info is there. These wipes are great! I can walk all day with no discomfort. The next day, my space bar, and then my Prinyt Screen key as well. 5mm cord handy. The real reason I bought this is to use in my luggage and check if it makes it to the plane before a flight. but mostly because I have a masochistic inability to be happy with my audio gear, not because theres really any reason to upgrade from these. An Update:I had worn these flip flops on a cruise and I really enjoyed them.
