Over the years in countless bike shops, I’ve heard the following disturbing phrases uttered to cyclists: “Get these cleats. You don’t have anything to worry about.” “These cleats have float you won’t need a bike fit.” “Get these cleats with float and they’ll take care of everything.” Unfortunately, phrases and versions of these sometimes false reassuring comments are shared in not only bike shops but in forums, local rides and social media groups. Consequently, it’s time to set the record straight and dive deep into the cleat adjustment handbook. Today we’re going to tackle the following:
- Define cleat rotation and float
- Review popular cleat float types and limits
- Overview why both are needed and some suggestions
SPOILER ALERT: Below is the 5-minute version of the entire article! If you’re more the visual type, this is your jam.
What is Cleat Rotation?
Cleat rotation is the physical movement of the cleat either clockwise or counter-clockwise to allow the foot to rotate in alignment with its natural orientation. Basically, allow the foot to point in the direction it would like to point. Generally speaking, the rotation of the cleat is similar on and off the bike. For many professional bike fitters, an off-the-bike assessment can provide an indication of the rotation required. For example, if you naturally walk with your toes out, you’ll likely require a similar setup on the bike.
For 3-hole cleat users of Look or Shimano road, if you have a “toe-out” natural gait, your setup will look similar to this photo below (bottom-right).

On the other hand, you may walk with your toes out but your cleats are set up what we refer to as “pigeon-toed” with your toes facing inward toward the bike. This can potentially cause significant discomfort or even pain, especially after thousands of pedal strokes.
Toe-in or “pigeon-toed”
To the original point in the article and to keep you on your toes, the logical question is, “Doesn’t cleat float solve this issue of toe-in or toe-out without requiring cleat adjustment?” The short answer is not always. Like any other bike adjustment, some people contain the innate and amazing trait of adjustability whereby the individual adapts to position changes. In most cases, the float is impacted by the rotation. If a cleat is not rotated properly, the foot may not be able to achieve the required, rider-dependent, foot position resulting in pain, discomfort, or injury.
What is Cleat Float?
Cleat float or pedal float is when the cleat rotates freely inward or outward while clipped into the pedal. The movement is categorized in different cleats by a number of degrees. For some companies like Shimano and Look, you can purchase cleats with varying levels of float or “fixed” cleats which meaning they are devoid of float. Float allows a person who toes in or out move the foot to a more natural position during the pedal stroke. Yet, float doesn’t necessarily solve all issues or allow enough range to meet the specific needs of an individual. More on that to come!
Shimano Cleat Float: 6 Degree, 2 Degree, and 0 Degree
Sam Richardson, Level 2 BikeFit Pro fitter, from Bicycles NYC describes Shimano cleat float levels below:
Sam expresses some significant warnings about less float requiring a bike fitting. While more float is safer because it allows increased space for the foot to function in a natural position and also may forgive cleat placement of a slightly less accurate rotation adjustment, float does replace a full bike fit (using the 5 main adjustments of the foot/pedal interface). An interesting note is the amount of float may be somewhat deceiving. Below is a diagram noting the specifics of Shimano float.

Contrary to some cycling lore, 6 degrees of float does not mean 6 on either side but 6 degrees total (3 in and 3 out). In addition, as you can see from Chad’s drawings the amount of movement affects the forefoot more on the 6-degree than the 2-degree. This is due to the change in the pivot point between both and also due to the amount of float provided. Shimano discusses this at length on their site as well. This prooves how increased float can provide a larger margin for error in natural foot movement.
Look Cleat Float
Look cleats provide an increased range with their 9 and 4.5-degree model but still sells a 0-degree. This again means for example in the 9-degree model that the foot can move up to 4.5 degrees on each side–not 9.

Speedplay Cleat Float
Speedplay provides the most amount of float (7.5 degrees in each direction for a total of 15 degrees) and it’s also adjustable. This higher level of float is imperative for Speedplay pedals since they do not allow for cleat rotation. Therefore when adjusting Speedplay cleats, it’s important to be aware of both the “heel-in” and “heel-out” settings as you can adjust both via the limit screws. Depending on the orientation of your feet, you may not be to utilize the full 15 degrees in each direction. Much like the drawings shown earlier in rotation, if the float is left open (maximum in both directions), the foot will travel where it wants to go but there’s a limit depending on the individual.
MTB, SPD and 2-hole Cleat Float
2-hole cleats like SPD (Shimano Precision Dynamics), Crank Brothers or Time Atac contain an area of float prior to disengagement. Each type provides different levels of float but again be cognizant of the total amount of float advertised is split between heel-in and heel-out. For example, the Crank Brothers cleats below show the range of their 6-degree float cleats.

Why is Cleat Rotation Important if Cleat Float exists?
Yes, I’ve been alluding to this throughout the article so here’s the point. As I pointed out in the video, just because there’s lateral float, does not mean a person won’t still experience pain or issues. If a cleat is not properly rotated, then it’s possible that the float will not allow enough foot rotation to achieve optimal foot position. For example, if you are a natural toe-out walker and your cleats are rotated inward, float alone is unlikely to solve the issue (especially with 3-hole and 2-hole cleats).
If this is the case, you’ll likely experience knee pain while riding most likely on the inside of the knee but more toward the back (see image). In order to avoid this pain, BikeFit Professionals are trained in the process of examining the cleat from a rear position and testing rotation to find the best rotational position. While this process is outlined more specifically in our BikeFit manual and courses, it’s imperative to recognize that float and rotation both need to be taken into account during proper cleat setup and alignment. If you’re curious about the process that trained foot/pedal professionals use to assess proper cleat rotation, here are a few pictures of fitters performing the task.
I’ve love to give you the easy answer to purchase a cleat with float and be done with it, but unfortunately, I’ve seen too many uncomfortable cyclists over the years with float who require proper rotation as well. Enjoy your ride! -Paul and Damon
Great discussion (as always!) Paul and Damon. We overflow with appreciation for all you guys bring to cycling.
We have noticed after a few thousand spin shoe/cleat setups that when we are looking at the rider’s gait their cleat position tends to agree, as Paul referenced– WITH ONE CONSISTENT CAVEAT. When a rider is sitting in the saddle there is a tendency for slightly less toe-out than their gait shows. We can think of two possible causes. First, the relative rearward placement of the hips when cycling vs. upright. Move your hips rearward right now and look down at your feet [especially evident if you stand on something slippery like a garbage bag!] you will notice your toes migrate inward in response. Second, the unloading of the lower body that is no longer fighting gravity to stand or walk when cycling tends to need less lateral support/less outward rotation. Both result in slightly more closed hips and a convergence toward the midline. So, if we see extreme outward rotation when standing/walking, we will set cleats less dramatically so. We have not had anyone return for cleat adjustments so it seems borne out by reality. Sometimes an extremely duck-footed gait ends up pigeon-toed on the bike. We can’t recall the reverse, a pigeon-toed walker riding duck-footed, unless their saddle is atrociously too low and their physiology is looking for escape from the compression. Anyone disagree or concur?
As mentioned always check rotation on the bike. Off the bike is a general view that typically points you in the right direction but again ultimately setting cleat rotation is done on the bike.
Having looked at thousands of indoor cyclists I don’t recall this trend you ae seeing off the top of my head, but it could be. I will ask one my colleagues who has fit about as many indoor cyclists as I and see if he noticed this.
Glad you are paying this close attention to this. The world needs more like you.
Well, the very most important factor to me is (float or no float) how easy is it to pull out of the cleat (and does float affect the amount of force or movement required to pull out?)
It is true that some people are not impacted immediately by float or rotation but it’s imperative to have it adjusted properly. As per your question, float does not impact the amount of force required or the movement. Many pedals contain a “spring tension adjustment” such as Shimano’s SPD (https://si.shimano.com/pdfs/um/UM-46X0A-000-00-ENG.pdf). This affects the force required to disengage.
Occasionally I have adjusted or reduced the float in the direction of rotating out to release from the pedal. I have set the cleat to disengage a little sooner with a cyclist or two that had limited mobility. It worked quite well but again there was a specific reason for this, and this is not a normal practice but a great help when needed.
Shimano does not divulge the float on their MTB SH51 and SH56 cleates. Anyone know what the float is, and are they different between SH51 and 56
Hi Kevin,
Both the SH-51 and SH-56 (multi-release) both have 4 degrees of float.
