The Solstice XT is our updated lightweight, FootShape cross-trainer ready for all-day action. Building on the comfort and style of the original Solstice, we've added a durable caged upper for improved performance. Like all Altra shoes, we kept the Balanced Cushioning and also added a full rubber outsole that works well both in the gym and on the run. With the Solstice XT, you get the athleisure look with hardcore performance. No matter your workout, this shoe is ready to take it on.
