When I bought my first pair back then, I was impressed with the quality of workmanship and high level of comfort. At first, this annoyed me to have to do, but I was just more comfortable and gun fire was much quieter. Im a size 6. I finally got it right on my third try. I have not tried bleaching as I dont want to use anything more than soap and water so they are now her grungy daycare/play sandals. I can easily see street signs 100 yards away, and the path in front of me is lit up thoroughly so I can avoid obstacles, debris, etc. Flexible, cushioned, and amazingly comfortable. Dont get fooled by the USB. Very easy to assemble, just make sure to have seems on legs on same side. I bought these for my 6 year old and my 2 year old.
