EVA midsole with a Diapad 3 insert in the heel for lasting cushioning.
RUBLAST rubber sole with reinforcements in areas that are prone to wearing.
Lightweight shoe, only 355 g. 3D mesh fabric upper (a supple casing that covers the entire upper for more comfort and breathability) with memory foam around the ankle. Thick and soft foam for a very comfortable tongue.
Midsole made from "compression moulded" EVA foam with "diapad 3" insert at the heel to provide durable comfort. In'Up insert at the front of the shoe for more dynamic forefoot cushioning.
PU and EVA insole for durability and less weight.
RUBLAST rubber sole with reinforcements in areas that are prone to wearing. PU reinforcements around the toes and instep to provide a durable upper that withstands sliding.
The shoes have been blind tested by a panel of tennis players of all levels. They evaluate the level of comfort, that is, how the shoe fits and how soft it is (from the very first time worn), on a scale of 0 to 20.
The "cushioning" star test
The shoes are tested in a lab on a machine that reproduces the impact of the heel when playing tennis using an 8 kg impactor. The greater the acceleration, the greater the impact suffered by the body.
The "resistance to wear" star test
The shoes are tested in the lab on a machine that has been specially developed to reproduce the type of heel, forefoot, toe, and instep wear seen in a tennis match. The more cycles are needed to reproduce the wear on the shoe, the higher the shoe's resistance rating.
