TIEM currently offers three different styles: The Slipstream (Cycling), the Via (Cycling), and the Latus (HIIT/Training)Both cycling styles, the Slipstream and Via, are built with SPD cleat compatibility to clip into most at-home, studio, or road bikes. Although both shoes can be used for indoor or outdoor riding, the Slipstream is designed with indoor cycling in mind, while the Via is designed to perform well in outdoor elements. The Latus is our training sneaker, designed for all other cardio classes such as bootcamp, HIIT, tabata, boxing, etc. or everyday wear. With a strapping system that's built to support lateral movements, and our patented TIEMCORE technology, the Latus gives you the versatility to handle any workout off-the-bike.
