Unbelievable quality, off-the-shelf and ready to go
The Cobra9 SemiPro is a semi rigid orthotic device designed specifically for cycling use. The varied contours and lengths available make it the obvious choice for the cyclist who wants a custom fitted cycling orthotic solution. They are made from dual density EVA foam wrapped around a contoured carbon fibre core. The Cobra9 SemiPro is light weight and space friendly yet durable enough to satisfy the most demanding cycling pursuits.
Cobra9 SemiPro provides direct mechanical force to the sole of the foot through the pedal stroke. The SemiPro shape has been designed to ensure the most comprehensive surface area for load distribution across varying foot types.
The shaping of the carbon fibre inner core allows loading under the entire foot including the arch to ensure we redistribute peak forefoot pressure and alleviate hot spots.
Carbon Fibre Inner Core
The heart of the SemiPro is a carbon fibre inner core that provides the structural backbone of the device. The inner core is light (10grams) yet stiff enough to deliver effective load for a more comfortable pedalling stroke.
The shape of the inner core has been meticulously designed with the pressures of cycling in mind. The pressure applied to the plantar surface of the foot works in conjunction with the shape of your cycling shoe to improve foot function. The narrow heel cup avoids bulking out your cycling shoe and while the carbon fibre inner core is stiffer and lighter then the foam/plastic competitors offerings available, there is still adequate flex to ensure comfort.
Dual Density Topcover
The Cobra9 SemiPro is wrapped in 2 layers of EVA foam. The upper layer is a lower density foam suitable for cushioning but with excellent resilience. The bottom layer which wraps around the fibre inner core is a higher density EVA foam designed to provide longevity. This sandwich of EVA foam around the carbon shell helps bed the Cobra9 SemiPro into your shoe.
Keeping the EVA bulk to a minimum helps keep the overall weight of the Cobra9 SemiPro to a minimum.
The Cobra9 SemiPro has been designed for further customisation. Adhesive domes may be added for further load redistribution in the forefoot. Because the shell is strong and semi-rigid, all additions to the base SemiPro will generate a far more prolific impact to the cyclist.
Wearing in instructions
When using your Cobra9 SemiPro devices for the first time, ensure that you go for a short easy coffee ride. Do not use an indoor trainer or rollers initially. Too much continuous pedalling at the start of your Cobra9 SemiPro journey is not advised. Allow 2-3 easy rides to settle into your SemiPro set up. Once this has been achieved, increase your distances gradually for the next 2-4 weeks. After this time, if you haven’t fully settled into you SemiPro devices, contact either Cobra9.com.au or your authorised Cobra9 retailer for further advice or modification.
