after year of speculate , I purchase this 1st pair of Birks not know what to expect . the cradle you foot be in , be at first difficult to get use to with the ridge but soon become comfortable . they may be good for walk anywhere that do not have pebble , because once a pebble find it way onto the footbed , you have to take off the shoe to shake it out . otherwise the comfort level be definitely outstanding . I have be advise to not get they wet , that for I at least , be a new concept when wear sandal . at this price , they be definitely worth a try .
