If a picture says 1000 words ...
There are many works to describe the knee tracking of the Giro d'Italia riders in this article?
I would like to just get their shoes and do a few fast adjustments ...
Viva il Giro!

In the world of Bike Fit
Here is a link about one of our favorite customers. You may remember their name as our top international dealer last quarter - La Bicicletta

Different approaches to 1 Problem
Paul got a call form a customer local to me and asked me to go and help him as he was experiencing lateral knee pain on his right side and some pain on and off on his left leg.
Once I arrived at the customer's residence I asked the usual questions, measured his feet for varus/valgus tilt and this is what the FFMD gave me: 0 degrees left and 5 degrees valgus right.
What the customer had placed under his shoes/cleats because he felt that his feet were "sliding off the pedals" were 2 wedges for valgus on the left foot and 3 on the right resulting in the knees to track incorrectly.
This is the orthodic that his orthopaedic doctor made him as a result of being filmed walking however his varus/valgus tilt was never measured. The left orthodic also had some degree of correction for a valgus tilt but not as extreme as the right.
The issue in this particular case is that the stance was not properly addressed at the time the cleats were mounted. I finished the fit by moving the cleats as far inward as I could in order to get more "support" under the client's feet so he would not experience the "sliding of the pedals" sensation. The best solution in this case is to go for Speedplay Zero's with a longer spindle to get the foot to be properly connected over the pedal. Since this has been his position for 3 years any changes towards a normal foot position may result in the nervous system and muscular system reacting to this as being a weird feeling.
While the philosophy at Bike Fit Systems is to "fill in the gap" and provide support under the foot by use of the cleat wedge or ITS wedge, I have heard of "specialist" in podiatry compensating the other way: so if they had a patient with 10 degrees of varus and orthodic with 10 degrees of valgus would be made in order to have the ball of the foot flat. Coincidentally enough over the week-end I was speaking to Dr Morelli of the Mapei Sport Service Center in Castellanza, VA, Italy about this same issue. He was seeing at their lab many riders "suffering" from knee pain that were fitted with orthodics that were made to change the structure of the foot instead of supporting it.
Of the last 4 fits, 3 of them had 1 foot with considerable amount of valgus! Two of them were almost identical in that they had 8 degrees of valgus on the left foot, 8 degrees of varus on the right and both riders required a Leg Length Shim to compensate for a shorter left leg.

Bike Fit - SPD cleats and pedals.
I think I echo the sentiment of others by saying that I prefer to work with almost any other cleat and pedal when it comes to bike fit. But I think when it comes to really trying to improve what we do - we must learn to embrace our weakness or area we like the least.
I personally took this challenge and one of the results was the new V V 1 cleat, perhaps the most advance cycling cleat in the world. Here are some of the considerations for taking this challenge.
Market size and share - The SPD market is the largest market of pedals in the world. I will restate that as there are more people (A LOT MORE) riding some sort of SPD or SPD knock off than any other cleat and pedal. This is a huge and relatively untapped market. It really is ours for the taking.
Mtn bike fits and control - When it comes to so called mtn bike fits I often hear people say bike fit is not as important as a road bike. This could not be further from the truth. What controls a mtn bike more, than lets say seat height or position, is the foot/pedal interface. Your feet control the bike and are far more important for control of the bike than they are on a road bike.
The kicker – in spite of the fact that the connection is more important the platform size is small and not as stable. – The relative contact surface of an SPD cleat to the bottom of the shoe is so minimal. Often efforts we put into working with this cleat have been tough. Even when we get a desired adjustment it can be difficult to make sure everything maintains its setting. One less variable (incorporating a wedge into the cleat) eliminates one of the adjustments we need to control when working with SPD cleats. In other words it should be easier to address by eliminating one of the reasons we may tend to shy away from SPD type fits.
Here is a link to some early success with the V V 1 cleats. I hope you too will enjoy this type of success soon. http://hypercatcycling.wordpress.com/
