Many athletes suffer from cold feet.
Athletes have several options to deal with cold feet. The first, most commonly tried, is different socks. Some simply try thicker socks or two pair. Others go straight to thermal type socks made with wool or some other blend of yarns.
Footwear is often a contributing factor to cold feet. Today’s running shoes typically have a part-mesh upper, which lets cold air inside the shoes. And since the mesh is over the forefoot and toes, they get cold first. Secondly, footwear that is too tight, because the wearer has thicker than normal or two pairs of socks, causes constriction and impedes circulation.
Something else often tried is disposable chemical warming packets. These seem inexpensive at first, but because they are single time use, the costs add up quickly. Packs of 10, using two at a time, go fast. And they often don’t generate enough heat to provide overall warmth.

Another option for cold feet is one of the new lines of heated insoles. One major heated insole companies is Thermacell. While not cheap, if you suffer from cold feet long enough, you’ll likely be willing to spend the money for warm feet. Their insoles are water resistant, and durable. Once they reach the desired temperature, they turn off and then turn back on when needed. The insole’s top is molded and cushioning while underneath the inner components, is an insulated layer to keep heat from escaping. The insoles can be trimmed to fit shoes or boots.
Thermacell has two types of insoles:
Heater Insole Foot Warmers with embedded batteries that can be recharged 500+ times. Operated by a wireless remote control, they operate with lithium-ion polymer batteries embedded in the insoles. The three options are no heat, medium (100 degrees F), and high (111 degrees F). Each charge will last up to five hours with a medium heat setting. The batteries can be recharged at least 500 times and recharges in four hours or less. Their website currently offers a free car charger with every pair purchased while supplies last. These Heated Insoles retail are selling for $129.99 and come in full and half sizes. Click here for Thermacell Insole Foot Warmers.
ProFLEX Heated Insoles with removable batteries for extended use. They have the same features as the above insoles, same heating options, same wireless remote control, and the same rechargeable batteries. The first main difference is that the batteries are removable and replacement batteries are available. The second difference is that these are charged with a USB port or the customary wall charger. These insoles retail for $184.99. Click here for Thermacell ProFLEX Heated Insoles.
Thermacell’s insoles have been tested by SATRA, the worldwide leader in footwear research development and testing. SATRA found the insoles resistant to moisture, verified the five hour run time, and that the insoles maintain foot comfort with their heating.
If you feet are always cold, I’d look at these Thermacell insoles to help keep them warm. These could work in running shoes, cycling shoes, and hiking boots, as well as your normal everyday shoes. Make sure to check the insole thickness inside your shoes to see if you need to wear a less bulky sock.
