THE ROGER Clubhouse Pro

Clay court: Typically deep red in color, clay courts are normally made of crushed stone, brick or shale. They offer reduced ball speed, a higher bounce and the ability to slide. So players need an agile, supportive shoe with grip in just the right places.

Hard court: As the name suggests, hard courts are generally made from asphalt or concrete. They offer a high, predictable bounce and a fast playing experience, so players need a stable, lightweight shoe with plenty of grip.

Multi-court: Featuring a versatile herringbone tread, multi-court shoes provide reliable grip across a variety of surfaces. Ideal for most racket sports, they can be worn on clay, indoor and hard courts.

Heel to toe drop is the difference in height between the heel and the forefoot. In a shoe with a drop of 7 mm, your heel will sit 7 mm higher than your forefoot. Shoes with a lower drop tend to place more load on the ankles and are generally better for midfoot and forefoot strikers. Shoes with a higher drop tend to place more load on the knees and hips and generally better for heel strikers.
