ShockBlockers® Testing and Performance


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."

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.

ShockBlockers Independent Fabric Testing


Common complaints about insole inserts are that feet become hot, moist and uncomfortable. The ShockBlockers Insole Insert's fabric solves these problems through its combination of low-friction, high-wicking, and extremely durable textiles.
