Just slip in! The BIRKENSTOCK Callan is a practical slip-on shoe that’s also perfect for wearing without socks thanks to its unlined finish that prevents rubbing. The casual low shoe features elastic inserts which make it easy to put it on and take it off in no time. The upper is made from soft suede.
Suede is a split leather with a napped finish. It has a velvety surface and is very soft to the touch. It also boasts a high moisture absorption capacity. Suede is softer and more flexible by nature and does not have the same stability as smooth leather. The stability of suede also varies from hide to hide. This does not constitute a material or production defect.
