It is lightweight and comfortable to wear. The front does dog into your toes a bit but starts to loosen after use. The assembly was simple and we love it. I have not felt like they would fall out at all. Im a size 18, about 221 lbs, 42C with about a 42 waist. (the rubber cord part) I love them regardless, next time I will try how the size 12 feels. I have a trek bike. just can sway side to side a little. They are the exact same shoes in my local high-end shoe store though.
