If you want toe clips the platforms aren't going to be a good option. Just go with one of the MKS styles others have suggested. I just suggested platforms because I thought it would be a better look on a cross check with ultegra than a set of retro quill pedals, but hey, it's your bike.

The pins are replaceable, but they are not adjustable height. The strap holds your foot on the platform. I only use them occasionally in the winter with boots. It's not as secure feeling as toe clips with the strap ratcheted down, but it does allow you to pull up somewhat. I think they are intended for the fixed-gear crowd so they can skid their fixies with skate shoes. I would like them better than messing around with toe clips for a trip to the store. But I used toe clips for decades so I understand it's not that big of a deal.
