All Stoko products provide the same medical-grade bracing support, leveraging our Embrace System™ technology. There is no difference in support between our products; the technology is identical.
The K1 Summit is engineered to deliver support and warmth, keeping you active and fresh all day on the mountain. It was designed for snow sports, such as: skiing, snowboarding, and cross-country skiing.
The K1 Flux is engineered to deliver support in sweaty, high-intensity sport, getting you back to activity and overcoming injuries that get in the way. It was designed for high-intensity sports, such as: hockey, football, and basketball.
The K1 Tempo is engineered to deliver support, keeping you active, cool and equipped with the essentials while in warm environments. It was designed for warm activities, such as: running, hiking, and training.

The K1 provides support and stability to the body like traditional knee braces; however, the K1 achieves these outcomes through different means. The K1 relies on tension throughout the Embrace System™ to generate support, which is made up of cables that are integrated into the tights. The result is support that moves with your body and doesn't make you compromise on comfort, aesthetic, or support.
