SPD

Works fine.

Works, though they are not super tight and they move slightly. Not sure if they will hold up over time. Especially if they are taken off and on.

Exactly as advertised seem to work well for their intended purpose

The plastic is very brittle. I installed them and tried to ride with my clip in TMB shoes hoping I would be able to ride these as the flat side and flip them over to clip into the other side. Nope. Will not allow me to clip in the other side. If you want to install these and ride them without clipping in, they will work to do that. But you can't get them back out without them breaking. I will be sending back the broken pieces for a refund.

Original Review below. UPDATE: After posting my review the supplier reached to me and offered a full refund for these. While this was more than generous, I do intend to try to use them as modified / noted below, so I don't feel right taking the credit. I did up my review from 2 stars to 4 though because of their customer service. Just know if you have pedals like my XTRs, where the screw on the other side sticks out, these adaptors will not work without modification. I ride clipless pedals on my mountain bike, but the pedals are not comfortable with out clipless shoes on. I do a lot of events a year where you are parking further away from the event and riding the bike back to the after party or packet pick up is easier than walking, just uncomfortable on the feet. It's not a big deal in regular shoes but was looking for more of platform for comfort. Came across these problem solvers. Out of the package they did not work with my xtr pedals. The front was hitting the front of the pedal not allowing it to toe in. Luckily they are just delirin and a hack saw and file cleared enough material to make them work. So that was strike one. The second strike was that they are small. They're no wider than the pedal, only longer. I'll give them a go for now as I own them, but wish I would have went with the larger metal ones and added my own cleats. Having to use a tool to put these on and off also is a bit annoying but not the end of the world as I'm not sure how the metal style will work...

Super easy to install and only took a few minutes to adjust for a perfect fit.

Very tight fit for my Trk SPD pedals even on the lightest retention setting. I have to use my multi to to release them. I've had others that could be twisted out by hand at low retention settings.

Snaps in easy with a little flathead screw driver leverage between the pedal and mount clip - like a shoe horn. Nice to have one side ready if wearing clip-ins and the other side for flip flops or sneakers.

Works great, easy to get into the pedel, harder to remove, but recommend

Inaccurate description. This does not fit my XTR SPD pedals, and it does not easily go on and off the pedal. This product is not as advertised. I should have read the other reviews before I bought this!

I purchased 2 pairs for my family as there are some days we don't want to use our mountain bike clipless shoes so I thought I'd try these 'in between' or 'hybrid' convertible platform adaptors for our Shimano SPF pedals. RESULT: * Product does not fit well with Shimano SPF pedals. * Very difficult to install, even with completely 'dialing' back the adjust nuts. * Once you got it in, good luck getting it out. I spent 30 minutes trying to get it out per bike. * Durability is not there. I'd go with metal vs plastic or go completely to a new pair of bike pedals that have both clip and clipless built into the pedal. Do not buy these.
