The answer as to why is 'rocking torque' or 'rocking couple' as it is sometimes called. Basically, the further your foot is from the pedal axle, the more effort it takes to stabilise your foot on the pedal. With your 13mm shim, as you drop your heel, that foot being further from the pedal axle, will rotate further behind the pedal axle for a given degree of heel drop than the foot without the shim. The 1 mm further back (relative to foot in shoe) for every 5mm of shimming 'rule' is a reasonably effective rule of thumb. Like all rules of thumb, it may not be correct in individual circumstances. Some riders can get away with less, some need more.

Wondering what if any information/thought there is out there about what cyclist should do to correct position for feet of significantly different length (half a US shoe size or about 1cm). My leg length has been measured and is very close if not equal but I feel out of balance when all things are set the same. So I have tried new cleat fore-aft positions and shims but nothing seems to put me in the 'perfect' position. I am a 38 yr old racer.

If you are using a single size of shoe I assume that it fits the larger foot well. That will mean that it will be impossible to gain a good cleat position for the smaller foot as the cleat on the shoe of the smaller foot will have to be much further back on the shoe sole than the cleat of the larger foot. You will need to buy two pairs of shoes in different sizes and use one from each pair that fits the appropriate foot well or invest in custom shoes.

You could possibly use Speedplay pedals in conjunction with Speedplay part no. 13330 which are alternative baseplates that allow up to 14mm more rearward adjustment than the standard Speedplay baseplate. I can't guarantee the Speedplay option will work and think it best that you have a shoe on each foot that fits well enough for the shoe to be an extension of the foot rather than have the small foot floating around in a shoe that is too big.

Whenever I ride I get this pain on the outer side of the sole of my left foot. Only the left foot. It feels as if some tendon or muscle or something on that part of the sole were under strain. The pain comes after just a few minutes of pedaling, tends to get worse during the course of a ride, and doesn't go away until after I stop riding. It doesn't really matter whether I am pedaling hard or easy.

I have experienced this problem for years, but I simply put up with it. I recently got a new bicycle, new pedals and new shoes, all of which are quite different from the ones I was using before, and I was hoping that those changes would somehow make my pain disappear, but the problem persists. (In case it helps: my old shoes were a fairly inexpensive pair of Nikes and my old pedals were a pair of Shimano Ultegra; my new shoes are Sidi Ergo2 and my new pedals are the Look Keo).

I bought a new set of wheels (2008 DT-Swiss RR-1450 Mon Chasseral) a few months ago. They are about 500grams lighter than my previous set (2006 Fulcrum 5). These DT wheels have a nice light feel while climbing and accelerating. However, I have noticed that they don't sprint as fast as the heavier Fulcrum wheelset. I run this test using the same bike, same tires/tubes, same gear ratios, on my rollers, on the road, with both DT and Fulrum tested first, and over a flat-ish 250 metre sprint the Fulcrum wheelset more often than not wins.

I don't believe their is anything wrong with the DT wheels; they feel almost as equally stiff, and when I free spin the wheels both DT and Fulcrum go about the same number of revolutions. This finding seems to go against cycling conventional wisdom. I would have figured that the DT wheels being lighter would have a lower rotational inertia and hence would be easier to sprint. In contrast, my deep winter diversion (this test) is leaving me with the feeling that higher rotational inertia is more advantageous in a sprint.

The only experience that I have had that is relevant is in the early days of Campag Shamals and Mavic Cosmic (early aluminium 39mm deep versions). Much to my surprise I found that despite the heaviness of the wheels, my climbing times up regularly ridden hills were unchanged providing I stayed on top of the gear. Descending I found them an advantage in increased stability which I put down to increased gyroscopic inertia of the heavier rims and wheels. Dunno if this is relevant but that's my two cents' worth.

First of all some background on me I guess. I am Male, 28, just a tad under 6 feet tall and weight 70 kilograms. I took up Cycling just over 2 years ago. I played cricket ALOT when I was younger, which led to some injury problems (Shoulder Reconstruction at 17, two lots of key hole surgery to my left knee to clean up the joint) and during one of my re-hab periods following surgery to my knee my physio suggested that running was no longer a good option for exercise for me and to try cycling.

I didn't take cycling up at the time, but a few years later my new partner's brother, who is a professional cyclist got my interested, and I have been riding ever since. I am not a person to do anything in half measures, and quickly set about getting myself fit enough to race. I do about 300 to 400km a week and recently contested my first road race. My entry into racing was set back longer than I would have liked after a training crash in January 2008 that badly broke my right clavicle.

Now to my problem. During a heavy training spell last year around August I started having discomfort under 1st Metatarsal of the big toe on my left foot, got worse to the point of having to abort training ride. On the advice of some informed people I tried moving my cleat position, both back and forward with no success in relieving the pain. I tried different innersoles in my shoes, with no change, but this led me to wonder if my shoes were to big.

At this time I had lost about four kilos from when I purchased the shoes (Sidi Ergo 2's, size 46) so I started running a second set of Sidi innersoles on top of the stock ones, this seemed to solve the problem. I still decided it would be a good idea to consult my doctor, had an x-ray and a CT of my left foot, which discovered sesamoids under the 1st Metatarsal, these are 2 useless bones under the ball of the big toe. Apparently, while not an overly common diagnosis, it was nothing to be concerned about. So I went on pedalling (with the 2 innersoles in each shoe) and haven't had any further problems other than some mild tenderness from time to time.

I am now starting to wonder again if my shoes are to big, I have now lost seven kilos since buying my current Sidi shoes. My first pair of serious shoes were a set of Specialized BG Pro (2 Velcro Straps, 1 Ratchet Closure) in size 45, these were destroyed in my crash, and replaced with 2007 Sidi Ergo 2 shoes which I have had for just over a year. I am going to replace the Sidis and need your advice on what to replace them with. Being that shoes represent a big outlay I want to make the most informed decision.

I have looked at the Heat Mouldable Shimanos, Checked out Bont's A-One, I also considered the Specialized Top End model with the Boa Twist Closure. I was very happy with the Sidis and would have another pair if the only issue with my current one's is sizing. The biggest problem I have with shoes is my feet are very narrow, I have been told that Northwaves are not a good idea due to there width in the forefoot, again this is something that led me to the Sidis, I was told they are good for narrow feet.

Sorry, I thought you may have been a Brendan G that I know slightly and who lives in Sydney. If you were, I was going to suggest that you come in and I would fix the problems. To add to Scott's advice; cleat position plays a part in how severely people with an issue like yours affects them. What I would suggest is moving your cleats further back on the shoe. Check out this link and this link that will provide some guidance for doing that. Let me know how you get on.

The cleat position articles you included I have read in the past, when I first started to have the problem with my feet (Left foot first, last year) and was unaware at the time that I had the sesamoids. I, like lots of other people used the "Ball of foot on top of pedal axle" rule, so when I read these articles was hoping for some relief. I moved my cleats back in small increments, 2mm's at a time, until I got to the 11mm's suggested for 46-47 size shoes.

Unfortunately, and to my dismay, the further I moved the cleats back the more pain I got in my feet around the area of the sesamoids. The problem seems to be that the sesamoids are mobile, so can be moved with some pressure with your fingers. There are 2 in each foot, if you drew a line from the ball of my Big Toe to the corresponding joint of my little toe, the sesamoids would run along the line, side by side. When looking down from my point: Excuse the rough drawing, if this is my right Big Toe ….

The sesamoid on the left, which is the one on the inside of my foot seems to get pushed further to the left and causes pain from the its original site to around the side of first Metatarsal, right around to the top of the joint. So pretty much the whole inside half of the first metatarsal joint get incredibly sore. To give you an idea of how much pain it causes, when I broke my collar bone last year I didn't bother with pain relief, but when my right foot flared up last week, I had to take something for the pain.

After getting the advice from Scott I started to have a big of a look at what sort of inner soles other shoes come with. The Sidi Inner Soles are unbelievably thin. A good mate of mine rides Specialized shoes, and I pinched one of the inner soles out of his shoes for a look, and the 2 Sidi Inner Soles I am currently using is not half the thickness of 1 Specialised inner sole. Running with that I ride for the first time yesterday in over a week in a set of his Specialized shoes (size 45) with no pain. Admittedly there was little Big Gear work, and no big climbs, it was just our normal coffee shop social ride.

I'm sorry that moving your cleats back didn't work. Some people have very touchy sesamoids but I have found this is rare of itself. If cleat position isn't the reason, then the two most common other reasons are a seat height that is touch too high causing the rider to sort of push with the toe at the bottom of the pedal stroke and poor foot cant on the pedal which can be addressed with wedging. I would persevere with the thicker insoles and if that solves the problem it is either inherently touchy sesamoids of a seat that is a touch too high.
