Birkenstock Utti Lace Suede Leather

Suede: Leather with a characteristic brushed finish and a soft, velvety texture. Unlike smooth leather, it is produced from the inside of the leather, which gives the material an unmistakable softness and suppleness. The main advantages of suede footwear include high breathability and the ability to adapt quickly to the anatomical shape of the foot, making the shoes comfortable from the first wear. Suede stands out for its depth of colour and gives the shoes a premium look. In order for the material to retain its properties and beauty, regular impregnation is recommended to ensure protection against moisture and dirt.

Microfiber: (Microfibre insole) is a highly functional shoe insole made of synthetic fibres that are thinner than a human hair. This material has an extraordinary ability to wick moisture and sweat away from the foot, keeping the foot dry and preventing blisters. The microfiber surface is very soft to the touch and provides a luxurious comfort feel, similar to brushed leather (suede) but with much greater durability and easier maintenance. Its breathability and quick-drying properties make it ideal for sports and leisure footwear, where it provides an optimal microclimate inside the shoe.

Polyurethane foam: (PU) is a high-performance midsole material known for its exceptional dimensional stability and durability. Unlike lighter foams, PU does not break down even after hundreds of kilometres and retains its cushioning properties. Thanks to its higher density, it provides excellent stability and support, which is crucial for heavier runners or hikers with a load. It's the ideal choice for durable outdoor and work footwear where foot protection and maximum resistance to mechanical wear is a priority.

Rubber: The rubber sole is a traditional and highly reliable element in the construction of footwear, valued especially for its extreme mechanical resistance and grip. This contact layer is made of natural or synthetic rubber, which is characterized by its high density and elasticity. Due to its physical properties, it provides excellent traction on a wide range of surfaces, from smooth asphalt to unpaved terrain. In addition, the rubber is naturally waterproof and resistant to temperature fluctuations, ensuring stability and a secure stride in a variety of climatic conditions.
