Developed with Andy Pruitt from the Boulder Centre for Sports Medicine the BG Footbed system improves efficiency increases comfort and reduces potential injury. This system allows any rider to achieve a semi-custom fit in their cycling shoes combining advanced insoles with Varus/Valgus wedge shims to align cant angle—an upgrade to any cycling shoe. By standing on the Specialized “Arch-O-Meter” a rider can determine the optimum level of foot contour: “+” = minimal (the standard BG footbed contour available in all our shoes). “++” = moderate. “+++” = significant. By combining the correct contour insole with an appropriate amount of BG shims the rider can alter forefoot angle to optimise biomechanical foot/knee/hip alignment. (+/- 1.5mm Varus/Valgus wedges included).
Paul Smith Corridori Cycle Sport:
“A Varus forefoot simply means that the fore foot is not flat, but raises slightly towards the big toe, infact the majority of us do not have a flat forefoot; Valgus is the opposite of the above and far less common.
Specialized BG shoes (so not the trainer styles) have varus wedge built into the outer sole to allow for this. BG shoes for me reduced knee twitch towards the top tube at the top of my pedal stroke, with a flat sole I found that it did just that as my foot pushed back down on the sole, effectively as my fore foot was unsupported it collapsed down onto the flat sole as I started to push down over the top of the pedal stroke and my knee would twitch towards the top tube as it did so, with the support of a varus wedge this was all but eliminated, I also used a different insole to allow for the fact that I have standard arches, most shoes, Speciazlied BG included, normally have to come by default with insoles that are set up for flatter arches than I and indeed most of us actually have.
The hard wearing dual density BG Footbeds also have a metatarsal buttons support, many complain of "hot foot", especially on long rides, a burning and often quite intense pain where the ball of the foot is in contact with the pedal, the metatarsal button support will help reduce and often eliminate this completely.
If required you can use shims in other brands of cycling shoes to support a Varus or Valgus forefoot, care is needed to make sure you use the correct type of Shim of course, that must relate to both the type of shoe and forefoot..
There is a quite a simple straight forward way check what type of forefoot you have, all you need is a friend, straight edge and a chair; simply kneel on the chair with feet dangling over the end, making sure knees are level, ask a friend to place a ruler/straight edge across the forefoot and it is then easy enough to see, after which it is then easy to work out which shim, if any, is required. For sure a Specialized BG Fit centre would always make sure that you needed Shims by observing your pedalling action, but it is indeed often the case that if you have an unsupported forefoot you will generally find an improvement if it is then supported. As well as an improved pedalling action a comment often made is that the rider will feel more planted and secure as the connection to the pedal platform should become more secure.” |
