Pedals - Shoes

[Joseph Iannazzone]

I've been riding Speedplay Zero pedals on Sidi Genius 5 (non-carbon) shoes for the past 2-3 years. I've started to have pain on the ball of one foot and am looking for a way to decrease pressure there. I'm going to try a pair of Shimano shoes to see if there is an issue with decreased sole stiffness in the Sidis. Does anyone have suggestions, perhaps based on experience, on any changes I could try to fix this problem?

There are lots of articles about the relative platform size of the various pedal systems; most point out that the Speedplay platform is actually in the cleat rather than the pedal. The still seem to have a slightly smaller overall contact area than the Look or Shimano SPD-SL systems.

A few years back, I was having tight calf issues. I moved my cleats
back some to decrease the tension on them.
Maybe you might could do the same and get the pressure off the ball of
your foot? It did make me a bit slower in the sprint because of not
getting full ankle extension, but I think it's fair. The Asianmon is
getting older and slower too. {:-D
But that's a topic for another posting...........

I had hot spots, pains, numbness, etc, for years. Thought it was normal. I went to Superfeet insoles and like magic, all the problems went away. I have since gone to a different brand and I like them even better. They are eFit from eSoles. Love them!
Good luck,  Paul Ozier

The insole plays a major part in shoe fit.  All my carbon sole shoes gave me some issues till i replace the insole. The best fitting ones i had was a molded insole and shoe by shimano.  But the stack height was a tad more than my normal.  Try replacing the insole with a insole that has better arch support.

Julie had lots of issues with feet pain and "Hot" foot.

She tried many shoes, and then went to a sports docter in Norcross,
who made up custom insoles, which did the trick.

Was not cheap(custom made, etc...), fixed the issues.

REI used to have semicustom inserts where they heat it up to conform to your feet

My shimano shoes were formed - http://www.youtube.com/watch?v=5YGTGsIOtGY

I solved the hot spot issue when I switched to carbon soles (Shimano
R221) and Look cleats.

i would try a simple arch support before any drastic shoe change

a good arch suport and a good fitting heel cup does wonders

I am big fan in less shoe rather than more.  IMO you should consider that the discomfort is related to position rather than shoe.  First, I would check the alignment of your foot and the spindle of the pedal.  I believe that the largest vector of force should be through the ball of your foot and the spindle.  Second, I would check that your position on the bike is appropriate.  Maybe you have made a change somewhere else on the bike that has changed the forces applied through your leg.  Thirdly, I would try to evaluate that you are pedaling properly or at least in the same manner you always have (before the pain, I mean).  I noticed that when I have not been riding for a while, I tend to flex my ankle differently.  I assume that this is due to weakness somewhere along the musculature.  I think "ankling" is a term used by people that pay attention to this.

All of this comes from my experience with the cleats for my TIME pedal system that I have used since I've had clipless pedals.  If the cleat wonders forward so I am pushing with my toes rather that the ball of my foot, I get a hot foot feeling.  Oddly, it is always the right cleat that moves.

Pain is caused by pressure

Pain = Pressure = Force / Area.  so in order to reduce pain  ==>  reduce force  -  distribute the force per stroke = smother cycling form

or  increase the area  = better shoe fit = distribute the contact area - includes arch and heel.  

If you want to know where are your heavy contact points  go to wal mart that has the scholl machine and see for your self where you need padding to get an idea where you need it.

Softer soles are only band aid - you give up some power for the comfort.  if you get a comfortable insole and distribute the force then the stiffer insole is far better because the pedal contact patch is not localized and distributed by the sole before it sees your feet

I think Mr. Ixiz and I can both be correct.  The area over which the force is applied is important. 

I would argue that the heel and arch are not directly engaged in the pedaling movement, especially the down stroke.  In fact, I suspect the the calf muscle is on tension during the down stroke effectively lifting the heel.

The truth will be shown.  How did it work out, Joe?

[ixiz]

Sure they are important 

Just analyze the pivot points and connect them with a line for simplicity

pivots  pedal axle - ankle - knee - hip -......

how can you get power transfer if the connecting lines are not providing support (stiffness)

[Joseph Iannazzone]

Thanks to everyone for your comments. I made some slight changes in cleat position that may have helped. It seems that the primary source of irritation is not from cycling. I've tried to convince Angie that it is house and yard work but she has not fallen for that one.
