At a rest stop I tucked it in around the straps and it stopped. Bamboo is more sustainable than paper and it also holds together better when you are using them. But sexy, strappy sandals. Like a sibilance on cymbal crashes. 3-1s each time. 0 stars for the price. Especially when I make old family recipes or try new ones. What this does well, is deal well with a wide range of music from rock, jazz, classical for home listening. I am a runner and like exercise very much. Beautiful shoe that is super comfortable.
