FRESH FOAM X technology
This technology was developed by our engineers following the analysis of data collected from tens of thousands of runners of all levels. Cushioning and comfort are the key words, whatever the distance.
Lightweight
The weight of a running shoe is a decisive criterion when choosing a product. The 840's light weight (288gr in size 43) is the result of optimizing the use of light, resistant materials in its design. We haven't compromised on comfort or durability.
Comfort and support
The use of Hypoknit Thermobonded mesh in the composition of the upper envelops your foot as closely as possible, providing optimal comfort. The weave of this mesh, which is more or less tightly woven according to the different pressure zones when walking, ensures excellent support.
Dynamism
The flex notches on the forefoot outsole provide excellent energy return and dynamism for your stride.
Resistance
To improve abrasion resistance, we use carbon-reinforced rubber in the composition of the outsole.
