These are actually great for the price considering you get two for one. I ride a bike to work and put my work clothes and shoes in my Timbuk2 bag. I was always worried about my work shoes getting smooshed on the ride so I got a two pair's of these. I have been using them for about a week now and they're great.

Make sure you get the right size, because they are not adjustable. They're spring loaded, so you can fidget a little bit to get them in there... but if you're to far off on the size... they won't work well at all. But I love them and would get more of these in a heartbeat.
