Snook-Ease Uses Phase Change Technology to Deliver Sustained Comfort and Warmth

    The human body was not designed to tolerate uncomfortable conditions and personal heating products never quite delivered as promised. Today however, a small Ann Arbor-based company, Snook-Ease (, is solving the problem. The company’s self-care solutions include slippers, socks and heated inserts. Warmed in the microwave, Snook-Ease inserts keeps feet reliably warm longer and safer than other products.

     A product designer with a technical background, owner David Ross relies on more than 20 years of experience to create and develop personal thermal management solutions. Ross’ passion and experience led him to create the company’s proprietary LavaTech™ Inside technology. From this technology, an insert was created that can be fitted into any shoe providing heat to this critical area of the body. 

    “Our goal is heating personalization- where you want it, when you want it and for as long as you want it,” explained Ross. “We knew the technology was sound, but to deliver greater value we had to find a way to sustain heating for a longer period of time.”

    Looking to extend the heating plateau time of his product, Ross learned of phase change technology and Microtek Laboratories. Microtek’s phase change technology capsules are of higher purity levels than competitive brands. Microtek’s robust capsules also won’t rupture allowing wax to seep into formulas. This means more reliable thermal management.
    Leveraging Microtek phase change technology, Snook-Ease has developed a warming insert unrivaled in terms of consistency and longevity.
    Snook-Ease inserts are shown to maintain a constant temperature for 30% longer. Ross’ solution is safe, affordable and practical for people of all walks of life. The product is especially beneficial for those with limited feeling in their feet, such as those with diabetes.
    “Thanks to Microtek phase change technology, not only is product performance enhanced; but we are saving on manufacturing costs as well,” concluded Ross. “The material is cheaper than silicone and thick enough not to seep through any fabric. This opens a world of possibilities for future product development. In addition to other heating products, we are exploring cooling applications as well.”
