Worn by Agnieszka Radwanska, the new Lotto Stratosphere Speed tennis shoe features Lotto’s new Stratosphere technology, created to provide even higher standards of cushioning and elastic return. It’s a cushioning system characterised by an elastic element in the heel counter, made of a special elastomeric mix with variable-geometry hollow hemispheres.
Compared to thermoplastic materials, the elastomeric composition ensures a more uniform mechanical efficiency in different weather conditions and consistency over time. Plus, it has a more effective autoadaptive capacity to different weights of athletes and players.
The Stratosphere Speed also comes with Enerturn, a shock absorption system in multiple-density elastic material that disperses the negative forces of impact and returns the accumulated energy to the player. Complementing the Enerturn feature is Lotto’s ReactiveArch – a dynamic sole with concave form for maximum cushioning of the impact forces, for stability when planting the foot, and reactivity during take-off.
A moulded EVA midsole and Ortholite insole provides resilient cushioning, while its upper is made of PU and nylon Ripstop material.
The Stratosphere Speed has an anti-abrasion compound outsole with a differentiated grip herringbone pattern that ensures exceptional grip on hard and fast surfaces.
