Why not get an extra pair of shoes and glue a toe clip and strap onto the uppers so it looks correct and you can ride clipless?:D

Sounds something like the old belt and suspenders

jyl says ... guess just have some aesthetic phobia about using big enough ones ..

the pinned Downhill MTB type are quite solid footing.. and Ive got 2 winters out of my Ergon pedals

in rubber boots . [gone a bit more casual with LLBean rubber moccasins] Their Huge pedal reflectors are great ..



Now use a pair of Campag BMX pedals on my Brompton with the Schlumpf kick pates on the cranks .
(cannot use the EZ shift plates with the stock folding pedal)

I think I agree with Fiets (it's hard to tell). When using the SPD side of the pedal, the toe clip is likely to hang down and scrape the ground in turns. Annoying at best.

If you want to try it, my wife's bike has M324 pedals. She's not using it right now (long story) so I'll loan them to you for testing purposes.

Really? I've seen a few people ride with toe clips that they don't always use, leaving the clips on the lower side of the pedal. They don't drag on the ground and certainly don't interfere with cornering. If you're wanting to do this to a fixie (you didn't say in the OP) and cornering is a problem then if your primary concern is about the looks put something smaller on.

That would work.

Back when I rode with toe clips and straps, leaving them on the underside of the pedals would always have them scraping along the ground until I flipped the pedal over. And, these were medium-size clips and size 9/43 shoes on a standard road bike with a normal height bottom bracket and 170 mm crank arms so nothing particularly oversize anywhere.

Why not make a type of platform where there is an SPD cleat attached and can be fitted with clips and straps which just clips in to the pedal. Just twist if off when using your SPD shoes. Or as an example you could just buy these or find something similar.

You could also mount a quick release pedal axle system that would make changing pedals fast and easy. http://www.bing.com/images/search?q=...xles&FORM=IGRE

The M324 has reflector mounting holes so you could probably bolt on the toe clips. The straps are harder because there is no mounting point on the inside of the pedal and routing the strap may interfere with the SPD side.

The VP X93 pedal looks like it has the inside strap mounting point but that's probably because they're reusing an existing platform (and it only comes in black).
