The XLP 2P BT Surround Comfort Set wraps our feet in a toasty haven while still sliding easily into our snug ski boots. The compact battery secures inside the double cuff for quick set-and-go, while the thin cord runs along the medial side of our foot, eliminating discomfort. With 4 heat settings we can control on-the-go through an app, this pair makes sure our toes never get too cold or too hot.
