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.
