The Alegria TRAQ Qarma2 features a new walker outsole versus the rocker outsole of the original Qarma. This lace-up sneaker tracks every step you take with embedded Q-chip technology by sending accurate information to the TRAQ smartphone app via Bluetooth for near real-time step counts. The Qarma2 also features a slip-resistant outsole to help protect against slick surfaces, and a padded collar for your comfort at the ankle.
