Etc.® Anti-friction Topping
Keeping feet cooler & drier!

“Shoe friction is unquestionably the single most common cause of foot discomfort.  Yet, ironically, with industry people it’s the least understood and least mentioned of the various factors involved in shoe comfort.  Few people (and even doctors) understand the dynamics of the foot inside the shoe.”  (William Rossi)

    

The infrared picture above left, graphically shows the temperature of a pair of feet that have been at rest.  The blue and green shades indicate the feet are at a relatively cool temperature.  The infrared photo above right is of a pair of feet that have just taken a rapid walk for 15 minutes.  Infrared technology shows the right foot is relatively cooler than the left foot.  The material lining the top of the insole that was underneath the right foot (cooler) was an insole made with etc.. fabric.  The fabric etc. is known to help control friction, so it kept the right foot cooler than the left foot, which used a conventional nylon lined insole.

The Super Light Insole employs the use of the etc. friction controlling top cover which is designed to make them SL Insoles much more comfortable than our competitors’ or original equipment nylon topped insoles.

Additionally, our deep heel cup & anatomically shaped arch support increase the surface contact between the foot and insole; this improves pressure distribution, also lowering the average amount of friction, resulting in a cooler, more comfortable foot.



THE TYPE OF SOCK WORN IS AN IMPORTANT FACTOR FOR COMFORT

The top surface of an insole is a big factor in the overall comfort of the insole.  The material used helps determine whether an insole will become hot due to friction, and whether it will contribute to causing blisters.  Another factor is the sock and the material it is made of, and how it handles moisture from the foot.  Even with the best friction controlling insole if the sock gets wet and its fibers grab the skin, all of the shear force is placed on the skin, and blisters will quickly form.  This is why Drymax® socks with the special Drymax® fiber are so good: because they do not get wet and cause problems.
