these be very comfortable sandal after break in . you need some time to make they fit , so do not buy a pair for tomorrow 's beach party . strap be very tight in the beginning . you may think they be impossible to wear tight . I recommend to get a pair in advance and wear they around house 'til they fit . I would say it 'll take about a week to make they comfortable to wear . but after they become yours , you feel like they be tailor make for you .
