Within the Caribou a removable 9mm washable recycled felt exists to ensure warmth and insulation for cold winter days. The removable felt increases warmth by trapping heat within its fibres to prevent heat loss to keep you toasty and warm on cold weather days. Completing the upper is a lacing system which locks down the midfoot to reduce in-shoe slippage so you can enjoy distraction-free strides.
