The rubber shell toe is a feature implemented into a handful of Adidas shoes; mostly shoes designed for basketball. Adidas shoes that include a rubber shell are as follows: Adidas Superstar, Adidas Superstar II, Adidas Pro Shell and Adidas Pro Model.
The purpose of the rubber shell toe is to protect, cushion and guard the toes; in other basketball shoes it is simple referred to as a 'toe guard'. Basketball is a sport which includes alot of jumping and landing; specifically, jumping and landing in close proximity to other players, who can land on an opponents foot. The rubber shell toe is a rigid rubber which offers a strong impact buffer for the toes, when compared to a standard leather, suede or canvas toe section. Using a rubber toe guard was not originally thought of by Adidas: the Converse Chuck Taylor All Star features a durable rubber toe cap, and it was added to the Converse Chuck Taylor All Star in 1949; 20 years before Adidas designed the rubber shell toe and released the Adidas Superstar.
