People choose Birkenstock shoes because they are very comfortable. However, not having the right size shoe – even if the shoe is a Birkenstock shoe – can end up causing damage to your feet. Shoes too tight will lead to the production of bunions, hammertoes, and corns. Shoes too loose will result in falls and altered gait.
Birkenstock shoes are sized differently from shoes in America. Here’s an easy way to think about Birkenstock sizing for men’s shoes: Size 7 to size 7-1/2 men’s shoes are a size 40 in Birkenstock sizing. Size 17 to 17-1/2 men’s shoes are a size 50. Each shoe size in between can then be calculated easily. Here’s a table to show you this sizing:
Men’s Shoe Sizes Birkenstock Sizing
7 to 7-1/2 40
17 to 17-1/2 50
Now let’s build the table from this one principle.
Men’s Shoe Sizes Birkenstock Sizing
5 to 5-1/2 38
6 to 6-1/2 39
7 to 7-1/2 40
8 to 8-1/2 41
9 to 9-1/2 42
10 to 10-1/2 43
11 to 11-1/2 44
12 to 12-1/2 45
13 to 13-1/2 46
14 to 14-//2 47
15 to 15-1/2 48
16 to 16-1/2 49
17 to 17-1/2 50
For any shoe size smaller than a size 7, subtract from the 40. Size 6 to 6-1/2 would be Birkenstock sizing 39 and size 5 to 5-1/2 would be size 38
For women’s Birkenstock sizing, consider that size 9 to 9-1/2 is a Birkenstock size of 40. Thus, you either add or subtract based on how far your shoe size is from size 9.

3 to 3-1/2 34
4 to 4-1/2 35

Kids Birkenstock sizes are anywhere from 37 (Men’s shoe sizes started at 38) for size 6 to 6-1/2 all the way down to 24. However, there’s something a little unusual about kids’ shoe sizes – size 8 kids shoes and size 8-1/2 kids shoes each have their own Birkenstock sizing. Size 8 is Birkenstock size 25 and size 8-1/2 kids shoe size is Birkenstock size 26.
