At MOTUS, the majority of our clients come from an athletic background. We’ve spent years working with athletes at all levels, and so we understand the underlying passion between an athlete and their sport. We know that nothing is worse than an injury standing in the way of activity and training. That’s why we’ve built a library of advanced tools proven to help keep our clients in the game, like Zelus insoles.

What are Zelus Insoles?

Many people turn to over-the-counter insoles, sometimes without knowing much about them, because they’re looking for more support under their feet. Insoles are meant to make up for the poor design of most shoes. One study from 2004 showed that simple insoles can improve excessive foot pronation when walking, compared to those wearing regular shoes without insoles.1 However, insoles can be about much more than cushy comfort. Zeuls insoles are designed with the athlete in mind, and offer a shock-absorbing cushioning that helps prevent injury and enhance athletic performance. We’ve chosen to offer Zelus insoles at MOTUS because of their outstanding quality and patented SmartCells design. SmartCells technology was invented in the late 1980s as a means for providing comfort and support for people on their feet. This innovative cushioning technology was first applied to mats and flooring. Later, in 2015, SmarCells decided to partner with another brand, Fastech Labs. This company has an extensive background in custom orthotics. By combining Fastech’s knowledge of foot support with the cushioning technology of SmartCells, the two came up with the Zelus insoles. The final design was completed in 2017, and features patented SmartCells in high-impact areas along with advanced orthopedic design throughout the rest of the structure. These affordable insoles are like no others on the market.

How do they work?

Zelus insoles use a combination of SmartCells cushioning technology and custom orthotics design to create optimum, affordable support. Zelus insoles come in several different styles with SmartCells micro and nano cells offering different degrees of support depending on the style. For instance, the Olympus LITE style comes with SmartCells on the heel and metatarsal area, but the Olympus PRO features SmartCells on the heel and the entire forefoot area. Your therapist at MOTUS can help you decide which style is right for your lifestyle.

The patented SmartCells technology provides the foundation for these insoles. It’s part of what allows these particular ready-made insoles to be so effective at preventing injury and fatigue, while providing support that will enhance your performance. Their design looks simple, like rows of tiny, soft cylinders. However, these little surfaces have a big impact on an athlete’s potential.

Part of what makes SmartCells work is their compressibility. This makes the material soft and comfortable to stand on even while it remains firm and supportive. The soft and stable design of SmartCells helps reduce fatigue so that you can stay energized and in the game.

The SmartCells portion of the Zelus insoles is also designed to absorb and rebound energy. Impact and sudden movements are cushioned by the structure. With each step or movement, the SmartCells in the Zelus insoles spring back energy to the body, enhancing your performance and working with your body’s movements.

What are the benefits of Zelus Insoles?

Having the SmartCells design centered around the areas with the highest impact is key to the Zelus insoles’ ability to energize and protect during play. This element is what makes these insoles so ideal for athletes. The SmartCells design can absorb up to 20% of an impact, and will return that energy back to the athlete. Shock absorption is also key in preventing overuse injuries for athletes. One study tested the effectiveness of shock absorbing insoles on military recruits starting a new training program. These recruits were at high risk of an overuse injury. The study found that the group who used insoles suffered significantly less overuse injuries.2 Another major benefit of Zelus insoles is their low price. These insoles are made with the same elements as custom orthotics, yet each pair costs well under $100. It’s an affordable fix to an important element of any spor. With an orthotic-grade arch support, Zelus insoles help support proper alignment, so you can build a better, stronger posture for an overall enhanced performance. Zelus insoles are made with high quality, durable materials. These insoles are crafted right here in the U.S., and are built to last much longer than normal insoles
