The Babolat Propulse 4 was developed in close collaboration with Andy Roddick, from the standpoint of design and game characteristics.

The new and improved Propulse 4 is an all-court tennis shoe that features a Michelin OCS2 high-abrasion outsole for optimal grip on any surface and the Side 2 Side technology, which gives the shoe better balance and lateral movement.

In stores in February 2013, the men’s version will be available in two colorways: yellow/black and white/blue. The women’s model will come in pink.
