I have had my first pair of Grassbow Air shoes for 8 months now. I have worn them hiking, running, cycling, camping, river romping, and they have surpased all of expectations! They fit true to size, give great footbed protection, great traction and sole. The soles have been very sturdy. Recently I wore these in the Virgin river in the Narrows in Zion National Park. They worked flawlessly, and upon exiting the river, dried in about an hour. Although these shoes were not designed for this purpose, I was extremely impressed with how well they performed! Great shoes!
