Technology Merrell EVA
Information
The name EVA stands for Ethylene-Vinyl Acetate . It is a type of copolymer that combines the properties of plastic and rubber. Sports brands use this material in the form of foam, from which they make midsoles and sometimes insoles for shoes.
The widespread use of this foam is due to its excellent properties.
- lightness → one of the biggest advantages that affects the overall weight of the shoe
- shock absorption → cushions every step forward, which your knees will especially appreciate; it can absorb shocks from your steps and thus increases comfort when running and walking (even over longer distances)
- flexibility → EVA material is very flexible and elastic, allowing natural movement and adaptation to the foot
- durability →generally this material is resistant to cracking and wear, but of course after really long use it can easily get crushed
- thermal insulation → keeps the foot warm in cold weather, and in summer resists hot surfaces
- water resistance → the closed cell structure of EVA foam does not absorb water, so this material is also used in outdoor shoes
- affordability → compared to advanced cushioning materials, the production of EVA foam is relatively cheaper, which is also reflected in the resulting price of the shoe
