Cluffy originally developed their insoles to help people with foot pain.  The insole was developed because there was no one else building an insole that was dealing with the root cause of many foot pains.  Cluffy insoles are very effective at eliminating many foot pains.

Recently we started to explore whether by allowing the foot to function more normally, with much better movement of the foot through natural postures there would be any improvement in athletic performance.

It made sense to us that if we were restoring normal movement and mechanics to the foot, that the foot would be better at doing what it was designed to do, provide a stable platform for balance, stability, and potentially improved strength as well.

We have tested athletes from Cheerleading and Wrestling previously, putting the athletes in their competitive positions and testing balance, stability of the knee and strength in a variety of muscle groups. (link to sports pages). We approached this topic with some degree of uncertainty.  However, what we found is that this insole offers benefits that are unique to its design suggesting widespread improvements in the parameters we have measured so far.

These findings are revolutionary for any insole product.  Other insoles do not have any measurable effects on balance, stability or strength, but the unique features of the Cluffy insole do allow all these essential athletic skills to improve.

While the correct shoe is important for any athlete, the normal insoles were previously used for foot problems and pains only.  The Cluffy Sport insole has expanded indications for sports and providing an increased sports performance potential you will not want to miss out on. The findings discussed below would suggest that most sports will see improvements in performance based on the shared importance of these skills.

CLUFFY Strength and Conditioning Findings Summary

These are the results from our recent testing of serious strength and conditioning athletes and some instructors. All testing was done with a handheld dynamometer measuring peak pounds of force applied. Please see the testing method and results below.

Balance testing – Results indicate the force required to push/pull the athlete out of balance.

Forward pull test. Athletes were easily displaced without the Cluffy Sport insole.  When the Cluffy Sport insole was added, it is nearly impossible to displace all athletes;
Back pull test .  Athletes were easily displaced without the Cluffy Sport insole.  When the insole is added, it is nearly impossible to displace all athletes
Weighted squats knee extended, push backwards, n=8, low -6%, high 135% average 46%more force required to displace with the Cluffy Sport Insole(CSI).             

Weighted squats knee extended, push forwards, n=9, low -30%, high 127%, average 60% more force required to displace with the Cluffy Sport Insole (CSI).
.Weighted squats knee flexed, push forward, n=9, low -9%, high 119%, average 40% more force required to displace with the CSI.
Weighted squats, knee flexed, push backwards, n=9, low 6%, high 106%, average 38% more force required to displace with the CSI.

Deadlift pushing forward, n=9, low -9%, high 69%, average 25% more force required to push forward with CSI.

 

Clean pushing forward, n=9, low 10%, high 82%, average 50% more force to push forward with Cluffy Sport Insole (CSI).
Clean pushing backward, n=9, low 1%, high 65%, average 22% more force to push backwards with CSI.

Overhead press pushing backwards, n=9, low -13%, high 83%, average 25% more force required to displace backwards with the Cluffy Sport Insole (CSI).
Overhead press pushing forward, n=9, low -1%, high 69%, average 39% more force required to displace backwards with the CSI.

The average improvement of all 10 balance tests is 39% with the addition of the Cluffy Sport Insole.

 

CLUFFY Strength testing

Results indicate force to break the initial position of the arm.

Arm in front raised to shoulder level resist pulling down, n=11, low -16%, high 62%, average 14% improved strength with Cluffy Sport Insole (CSI).
Arm to side raised to shoulder level resist pulling down, n=22, low -13%, high 118%, average 37% improved strength.
Biceps curl resist pulling arm down, n=17, low -12%%, high 223%, average 42% improved strength with Cluffy Sport Insole (CSI).

The average improvement in all 3 arm strength tests is 31% with the addition of the Cluffy Sport Insole.

Leg flexed at the knee, resist downward pull of the lower leg, n=3, low 13%, high 76%, average 35% improved strength with CSI.
Fire hydrant, resist downward pull of the leg with the hip abducted, n=3, low 0%, high 43% average 23% improved strength with CSI.
Knee drive, resist pulling flexed hip down, n=9, low 4%, high 92%, average 30% improved strength with the CSI.

The average improvement in all 3 leg strength tests is 29% with the addition of the Cluffy Sport Insole.

Lunge pushing knee out, n=31, low -1%, high 172%, average 40% more force required to push knee out with Cluffy Sport Insole (CSI).
Lunge pushing knee in, n=31, low -4%, high 74%, average 32% more force required to push knee in with CSI.

In Summary:


The average improvement of all 10 balance tests is 39% with the addition of the Cluffy Sport Insole.

The average improvement in all 3 arm strength tests is 31% with the addition of the Cluffy Sport Insole.

The average improvement in all 3 leg strength tests is 29% with the addition of the Cluffy Sport Insole.

The average improvement in knee stability is 36%.

These results indicate that there is an overall benefit of the Cluffy Sport Insole in both balance and strength. Surprisingly, the strength benefits carry over into the upper extremity as well. Even strength in the opposite leg was improved when we did the single limb strength testing. The stability of the knee was improved from side-to-side stresses, which may help prevent some knee injuries.

These results are exciting and have implications for many sports. For more information on the Cluffy Sport Insole or to arrange for a follow up call, e-mail us at info@cluffy.com or call us at (406) 274-7659.
