I think it is good to share this idea but based on my experience I feel it is also my obligation to respond. I like to try and exhaust my efforts improving stance width first. Considering that AT LEAST HALF (probably WELL over 50 percent) of the population of cyclists do not fit on standard “width” pedals it is no wonder people sometimes try the wedges the wrong way. Keo pedals, of all pedals offer perhaps the most limiting amount of stance width adjustment amongst pedals that actually offer stance width adjustment.
Yes some people will initially feel better with a valgus correction (over correction to be more specific) but I send caution due to the significantly increased misalignment this causes.
When you walk or run you choose your own stance width. When you get on a bike the stance width is chosen for you. However, most people never even get close to proper stance width on a bike and therefor prematurely go for other options.
There are some prolific abusers of incorrect valgus wedges use. Unfortunately I can also rattle off the names of cyclists that once used wedges this way but no longer do for many reasons.
In your case I hope you are OK even in the long run but I caution the misalignment may catch up to you.
I felt it necessary to share our experience with this. Please do not take this the wrong way. Considering the lack of stance width options available today the valgus wedges from one perspective may seem to make sense and I understand that. I once thought that way myself but after a lot of trial and error that has changed.
Thanks Swifty for the great reply... I agree 100% with your response regarding stance width, keos and misalignment.
Anyone using valgus wedging needs to exercise great caution, and needs to have every other fundamental of their fit right before adding these.
The brevity of my above suggestion probably neglected to emphasise the care needed to attend to the appropriate fundamentals before adding valgus correction to improve stance stability.
One advantage of the speedplays over keos i also failed to mention, which has helped me significantly was changing spindle length to correct my stance width accurately. This was easily done with speedplay zeros. I ended up using the 1/4 longer spindles on my zeros which then allowed my cleats to remain centred within the horizontal axis of the shoe. Following this correction the subtle valgus forefoot correction i have employed has been the final correction that has finished off the fit.
