I didnt expect this to be made of titanium given the cheap price tag but it is good quality for how much it costs and more than gets the job done. It super comfortable. I have a neuroma & can always buy Keen knowing they won?t hurt my feet. Maybe could?ve ordered a 1/2 size smaller. I get so many compliments from women. Soooo elegant macht es die Füße ?? The ugliness of Bose is really inexcusable. I stacked short boards on top of the longer boards and bungeeed them down. I wore these on a vacation in Europe recently and did a ton of walking up hills on cobblestone streets and so it wouldve been nice for it to feel more firmly attached to my foot, but otherwise they were very comfortable from day one. The sandal is so very very comfortable!
