With the Stirling model, BIRKENSTOCK offers a calf-high boot that takes its design inspiration from the classic Boston model with a leather strap and a metal buckle above the instep. A mix of materials has gone into the trendy shaft design, with fine and natural napa leather combining with smooth suede for a stylish overall effect.

Upper material: Natural leather
The natural leather that we use is mostly smooth leather, in some cases tumbled leather. This type of leather has many special characteristics, such as breathability, adaptation to the shape of the foot and durability.
Insole: Natural leather
Natural leather can be recognized by its untreated surface. BIRKENSTOCK purposely does not treat surface grains and other characteristic features. BIRKENSTOCK uses sturdy leather with a thickness of 2.8 to 3.2 millimeters as upper material.
Footbed material: Cork
Cork is a sustainable material extracted from the bark layer of the cork oak. This natural product is insulating and offers very good cushioning.
Because of its high elasticity rubber is very well suited for outsoles. Thanks to this property it supports the natural rolling motion of the foot. Rubber is also very robust and has good cushioning.
