Epoch Firewalker soothes, while Epoch IceDancer invigorates. Epoch IceDancer and Epoch Firewalker are two distinct products. Epoch Firewalker is a soothing cream, usually used on feet that are hot, tired, and sore. Epoch IceDancer is a light gel that leaves a cool, invigorating sensation on the skin. It is generally used on tired legs, but we have heard from various users that they love the product for their back and neck.
