We are flooded at our sports medicine clinic by stress related injuries due to running; a sport that has provided sport medicine clinics with up to 60% of their business. The cause of such injuries can be traced to repeated and sustained forceful impact of the feet hitting cement up to 3000 times in a 20 minute jog.

Recently, I conducted a 6 month study on EXERLOPERS to test their efficiency. Much to my surprise their bulky and unstable look gave way to a comfortable and safe fit. It takes about fifteen minutes to get used to them but once mastered they become part of you, much like a skate or ski boot.

You just have to jog on them for 1/4 of a mile to realize that you're heart rate has doubled and you're panting as if you just got off a squash court. There is no question that the amount of work done is at least 4 fold to that of running shoes only. After a short training period of 2 weeks you notice a drastic increase in your endurance and your burst of speed.

My greatest concern, being in sports medicine, was whether EXERLOPERS used as an exercise aid would help decrease the amount of injuries incurred during a jog, and my answer: a definite YES for 2 basic reasons.

  1. The impact phase is lengthened in time resulting in a gradual dispersion of the impact force.
  2. The actual impact force is largely converted to potential energy and stored in the spring to be released upon push-off.

Practically speaking, the effect is that of bouncing on a trampoline, giving your muscles a chance to contract and absorb the impact force and divert some of that energy away from the skeletal system.

One must be careful to use the EXERLOPERS on a flat, even and dry path and always make sure that they are well laced with a comfortable fit.

The other obvious advantage that can be drawn from these boots is their rehabilitative potential in quadriceps strengthening largely centered around knee pathology.

Of course more detailed studies would be needed to verify the benefits listed but my personal and objective finding give this boot a bouncy smile.
