The Milano is a good example of why Birkenstock fit should not be rushed. The footbed needs enough space around the heel and toes, and the straps should hold the foot without pulling everything down too tightly.
With Milano, the backstrap changes the feel compared with an open-back sandal. It gives the foot more security, which can be useful if you are walking more often, travelling or simply prefer a sandal that stays with you a little more firmly.
The team at Smiths can help you check the fit across the footbed first, then adjust the straps properly. Leather and Birko-Flor also feel different when worn, so trying them on can make the choice much easier.
Bring in your usual Birkenstock size if you know it. If not, we can help you work from the footbed up and choose the Milano style that feels secure without feeling over-fitted.
