So, went to REI and tried some Chacos. Now that I know how the straps adjust, the single multiloop strap design seems really ingenious. They were also low profile, light weight, and comfortable. Unfortunately, the foot beds just didn't work for me. The Unaweep wide and Updraft both had really uncomfortable pressure points. In the end, I chose another pair of Tevas. Hopefully this new pair does the trick for me. Anyway, thanks again for all the ideas. Those bedrock guys look pretty awesome!
