adidas ZX 5020 W

adidas Torsion® System: A lightweight thermoplastic arch in the middle of the sole that serves as a stabilizing bridge between the heel and toe. Its main function is to allow the forefoot and rearfoot to move independently of each other, mimicking the natural mobility of the foot. This technology provides arch protection, prevents unnatural twisting of the foot and ensures a smooth transition from heel to toe. The result is greater stability, less fatigue and more effective support during running and walking.

Leather: Natural leather is a traditional material resulting from the tanning process of animal hides and skins, which occupies a key position in the footwear and haberdashery industry due to its mechanical resistance, breathability and aesthetic value. The specific reticular structure of the collagen fibres allows the material to adapt to the user's anatomy, resulting in optimum wearing comfort. As a hygroscopic material, the leather naturally regulates moisture and ensures air circulation. The appearance and functional properties, such as the degree of water repellency or texture, are defined by the specific type of technological processing, which include smooth finishes, suede or nubuck.

Textile: The textile upper of the sneakers is lightweight, breathable and comfortable, ideal for everyday wear and sports. It ensures air circulation, keeps feet fresh and adapts to their shape. Often complemented with synthetic or rubber details for durability and support.

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.
