Slotted cleat, what standard is this?

I thought it'd be fun to ride the Dura Ace 7400 pedals on my bike. I thought it'd go great with my Look compatible Bontrager Classique shoes.

I ordered these cleats on eBay. The 3 hole pattern is way too small for Look. A little bit too wide for SPD. Came with bolts, not pins or screws. Definitely meant to be mounted to something.

What shoes had this pattern?

I think most of the cleats of that era were 2 bolts, but not entirely standardized.

You would mount those to shoes. The slot would catch the rear edge of a quill pedal, typically. We rode with cleats like those before Look came out. I found them nerve-wracking, because to work, you had to tighten the toe strap, making quick exit tricky. I normally left at least one of my straps loose. I was glad when Look came out and glad once again when SPD came out. Sometimes I think SPD is Shimano's best invention ever.

Clearly the previous owner Dremeled it out to attempt to get the bottom two holes on to an SPD shoe. The cleat itself doesn't have a scratch, so I assume this failed and never got ridden.

I know what they are. I just don't know what type of shoe they would mount to.

You could find an old pair of leather sole dress shoes at a thrift store, and drill them for that pattern; then use t-nuts for attachment.

My 1976 Vittorias have a three hole pattern, though the supplied cleats only use two of the holes. I think the three holes are to allow modern cleats, as well as older style with two holes. I bought these for Eroica only, but prefer normal SPDs for everyday riding.

The cleat bolt spacings during the later (bolt on) slot cleat era were generally proprietary to the shoe manufacturer. For example, if you had a Sidi shoe, you used Sidi cleats. There was a bit of overlap, and IIRC some generic cleats for the common brands were available, but it just wasn't standardized. No reason for it. There were not multiple pedal standards and systems to deal with. Any slot cleat would fit any pedal. I don't recognize these at first glance. Most shoes used one or two bolts.

I think the best path forward is to cut your losses and shelf these, then acquire some slotted cleats intended for the 'modern' 3 bolt Look pattern.

Those look like they would have the same pattern as Look. I don't think the drilling has changed from the mid 80s. Delta or Keep. Mine wouldn't fit.

Futzing around with a trashed old pair of Diadoras, I think they'd work with one Look hole and one SPD hole on a dual style compatible shoe.

At this point, I'm totally happy with Keo's on the old bike. The Classique shoes make brand new look totally retro.

If you have measurements of the hole pattern on the shoe, I could measure shoes.

Speedplay has a slightly wider hole pattern than SPD, but narrower than SPD-SL.

However, you'd probably need to drill the third hole.

I have speedplay specific shoes so I never used the adapters. Im sure I could modify those into slotted cleats or at least mount these to them. Seems like a lot of work for how seldom I'd use them.
