Birkenstock Mens Lugano Camberra 45

Camberra Old Tobacco 45 US M 12 UK 10.5 Regular Fit. New and Never Worn in Box. My husband has odd shaped feet and I was hoping these would work for him and it’s hard to find sandals that will stay on without straps but no luck. He had to grip with his toes too much. And then we didn’t return them in time. These are brand new in the box - never worn.
