I think these bags will work for me. I just wish they were clear instead of brown to make them more security friendly. I don't think the product really needs a toggle because you can always knot the string, I guess that option is also less security friendly, but better than the shoes falling out. I can't really comment regarding size because I wear a size 6 and don't travel with really high heels, over 2-3". I am happy with this purchase overall.
