I was wondering, which of these has the most float available? Thanks

Speedplay?

They're so expensive.

If you want float, just get the Speedplay.

For Shimano, the float, is in part dependent on the cleats. Here is what I've found.

SPD:SPD-SL:Personally, I'd use factors such as shoe style to choose between SPD and SPD-SL, rather than simply float.

stick with regular shoes and platform pedals , if Low cost is your highest priority.

Toeclips may also have a little flexibility.

I have been paying about $10 a pair for used SPD pedals, and they seem to have a lot of life in them if the bearings are ok. But the cost of shoes do add up. Winter shoes. Summer shoes. Oops shoes

I re engineered a Comfy Loose fitting shoe with a slot with an hour glass shape for angular float

that slot the whole width of the shoe . so stable , smooth . sole so it slipped in the toeclip pedal

with a comfortable supportive isole .. With the help of a shoe repar Guy that worked with me in his shop behind the counter

as we worked out the interchange between Ideas And standard techniques and Materials

So when the shoes needed a little work , the shoe repair shop I went into on the road, understood how to fix them again..

You actually found a cobbler?

I use SPD at the moment. I wanted an answer to a question and I got it. I'd appreciate it (and i'm sure others would) if you'd keep snide remarks to yourself.

Thanks, I use SPD at the moment but was thinking of switching as the SLs with their wider cleat are more compatible (or at least more are available) with stacks and wedges which I require with my wonky feet. I didn't want to end up with less float and potentially give myself another problem.

Where'd you find the SPD float info. I was looking on Shimano's site but could only find information on the SL float.

Its a Public forum.. kid.

Not so Much a start from scratch cobbler , but a repair shop ... He may still be there in Eugene,
some where around the REI store neighborhood, or was, at the time 90's?

more firmly established by now , perhaps also in the - drop it off and come back - mode that Most are using..

I had read about he SH51/56 info earlier, all I needed was to find it.
The SPD-SL info just came from a Google Internet search. I think I searched for: "spd-sl degree"

The Data came from the Wiggle site, but I think other websites have it too.

You know that SPD-SL shoes aren't really walkable don't you? You only walk with SPD-SL shoes if you really have to for a few steps.

When riding then yes, SPD-SL are better. If you value walkability then stick with SPD.

Thanks Clifford

Yes, I do thanks. Walking is also no longer a consideration (with luck on my side!) as I now have another bike I use for commuting.
