I have just come from a appointment regard back pain and be painfully wear my work pump when I have a call from the courier to say my Birks have arrive . I pick they up and wear they right away-thank God !!!! comfortable !!!!!!!!!! I wear they in the office lol use the excuse that I have back problem - which be true . I be grumpy all day until I put these sandal on . as for the size , they be wide shoe and I have a reg to wide foot . I may go to the shoe store to get some hole put in so I can fasten they tighter . be a size 11.5 and order a size 43 - just right .
