ShockBlockers® Insole Inserts


Oregon Aero ShockBlockers

ShockBlockers combine state-of-the-art designs and materials into superior anti-shock insole inserts. Our patented inserts were originally developed for the U.S. military and reduce feet and joint shock for anyone walking, running, or standing. And how do ShockBlockers do this?

Mike Dennis, Founder, President, and CEO of Oregon Aero explains: "When we walk, run or stand, we generate shock, which is mechanical energy. This shock can cause pain, stone bruises, shin splints and compression fractures. The goal of ShockBlockers Insole Inserts is to reduce the negative effect of this mechanical energy. The total energy generated can’t be reduced, but it can be converted into a form of energy that is more easily manipulated — in this case, into heat. A unique molecule in the ShockBlockers Insert polymer causes this conversion. The resulting heat is then captured by the proprietary fabric upper-layer of the insole insert. This fabric is woven in such a way that it also captures perspiration. Both the heat and perspiration are wicked to the outer edges and released and dissipated through evaporation. An additional component of the fabric reduces friction between the foot and the insole insert."

Oregon Aero ShockBlockers are available with 3 different levels of impact absorption. The right ShockBlockers for you depends on body weight and application. The three types are described below:

ShockBlockers Work/Sport Insole Inserts (Most Popular Option)


Oregon Aero ShockBlockers Work Sport Insole Insert

Recommended for people with active lifestyles and for anyone who engages in high-impact sports activities. These dual layer, 3/16 inch thick insole inserts reduce shock to your feet and joints while keeping your feet cool and dry.

Regardless of your weight, if you engage in high-impact activities choose our Work/Sport inserts instead.

ShockBlockers Deluxe Insole Inserts


Oregon Aero ShockBlockers Deluxe Insole Insert

Designed for feet seeking extra special care. If you have a foot injury or other foot related medical condition, please consult your health care provider before using these inserts. Extra Care Inserts are effective for walking, but not recommended for running or long-term standing. Inserts are 5/16 inch thick and feature 2 layers of our Visco-Kinetic material. One layer is soft and conforming and the other layer is firmer for shock absorbtion. Due to the extra thickness, Extra Care Insole Inserts require footwear with sufficient room. Users should try these inserts in new footwear before purchasing the footwear. ShockBlockers Extra Care can be trimmed to the exact fit with scissors. Complete instructions included.

Oregon Aero ShockBlockers absorb more shock than any other insole. Inserts are made using our own Visco-Kinetic™ material. In side-by-side drop weight test, Visco-Kinetic material absorbed more shock than vinyl sponge material, neoprene sponge, sponge rubber, and latex foams. More shock absorption means less wear to your feet and joints.

In addition to shock blocking properties, Oregon Aero ShockBlockers feature a proprietary top layer of low-friction, high-wicking fabric. The top fabric's exceptional wicking properties moves moisture and perspiration away from your feet keeping them dry and cool. This unique fabric has passed the 100,000 double rub test and is thermally bonded to the Visco-Kinetic base.

ShockBlockers are manufactured without the use of plasticizers. Because of this, ShockBlockers will not shrink, become brittle, or crack over time. Also, Oregon Aero's Visco-Kinetic material will not bottom out or become deformed after prolonged use. Users of ShockBlockers enjoy maximum shock absorption and comfort for the life of their shoes.

If you are not a soldier but your feet feel like they have been marching all day, how about giving ShockBlockers Insole Inserts a try? ShockBlockers Insole Inserts have been used successfully by the U.S. Special Forces, U.S. Army, Marine Corps, Navy, and the National Guard.

Tips for Getting the Most Out of Your ShockBlockers Insole Inserts


  1. Test fit your Visco-Kinetic ShockBlockers Insole Inserts in your shoes before trimming. If adjustments are necessary, you can use your shoe's original insoles or the included trimming guide as a template for sizing. Mark your ShockBlockers Inserts to size with a ballpoint pen and trim them to size with a pair of scissors.

    Note: ShockBlockers Insole Inserts can be used with or without the shoes' original insoles; whichever you choose is a matter of personal preference.

  2. Your ShockBlockers Insole Inserts must fill the shoe footbed without cramping your toes. The insert should fill the bed of your shoe from toe to heel. Check to be sure your heel has minimal slippage and your toes have adequate room — too much space can cause your feet to slide around inside the shoe. Insole inserts should fit snug and not have bends or wrinkles.

  3. After inserting your ShockBlockers Insole Inserts into your shoes, go for a walk or take a jog. Pay attention to how your feet feel. You should not feel any pressure points or pinches on your feet — especially around your small toes. If you do feel pressure points or discomfort, try a wider shoe or the next larger shoe size.

  4. During the course of a day your feet can swell and enlarge somewhat. Because of this, we recommend you first try your ShockBlockers Insole Inserts later in the day while wearing your usual socks.

ShockBlockers Impact Drop Testing


Impact drop tests were conducted on ShockBlockers Insole Inserts and leading brands of insoles with shock-absorbing properties. As shown in the table below, ShockBlockers Insole Inserts outperformed the competition in impact absorption tests. The results proved that ShockBlockers Insole Inserts offer 20% more shock absorption than the other leading insoles.

Impact Drop Test Results

ShockBlockers Inserts average Delta G's 106
All Other Insoles average Delta G's 134
ShockBlockers Inserts average Max +G's 87
All other insoles Max +G's 110
What do these numbers mean? The Delta G figures represent the difference between positive and negative rebounding. ShockBlockers Insole Inserts obtained the best performance with the lowest positive rebounding (Max +G's). Positive rebounding measures how many times gravity is multiplied during impact. In both cases, the lower the number, the better.

The bottom line: Oregon Aero ShockBlockers Inserts offer 20.6% more shock absorption than the other leading insoles.
