(TIML KICKS) Reebok’s latest collaboration finds the brand teaming up with Massachusetts-based David Clark Company, known for its pioneering protective equipment for space crews.

The two companies have come together for the creation of a extremely lightweight piece footwear for outerspace, dubbed the Floatride Space Boot SB-01.

The boot — which serves as the first evolution in space footwear in over 50 years — is currently being tested by astronauts. Its said to provide lightweight protection and support, and is exclusively designed to accompany the final space suit, which will shuttle astronauts to and from the International Space Station in Boeing’s new CST-100 Starliner.

It boasts a new Floatride Foam technology, developed by Reebok.

“Weight is a huge factor in space travel with just a single pound having big financial implications. Traditional space boots were made of rigid leather with firm soles and were not integrated into the actual space suit,” said Matt Montross, from Reebok Innovation. “Reebok Floatride Foam introduced three revolutionary elements to the space boot; it decreased the overall weight significantly, it brought the added comfort in a space boot and support that you would expect in a running shoe and it delivered a new level of sleekness and style.”

The new innovation and development journey behind the boot has led to another Reebok Running innovation, with a new runner called the Reebok Floatride 100g racer.

The Floatride Racer features a feather-lite midsole (weighing under an ounce), single layer engineered mesh upper and weight optimized full coverage outsole. Designed specifically with speed and function in mind, the Floatride 100g Racer is currently under-going testing and will officially launch in 2018.

However, the Reebok Floatride Run is currently available at retailers nationwide and online.
