I can provide pictures of the birkenstock.
The straps are made of smooth leather, (not Birko-Flo) in black, with Soft-Footbed (more comfy than the normal sole).
Whats Soft Footbed? For particularly sensitive feet we offer some models with the added feature of our "SOFT-FOOTBED", which Birkenstock developed in years of intensive research. A foam cushion is inserted between the flexible cork latex mixture, coated in sturdy natural jute, and the suede leather cover sole.This layer is marked by an exceptionally pronounced recoil function, which ensures long-life padding.
