[Steve in SLO]

Hi, all.
Today my buddy and I were riding our vintage Paramounts and complaining about our toe clips. His are the blue ones from Yellow Jersey, and mine are from I can’t remember where, but are in the pictures below. Both seem to have problems seating onto the cage because they are so soft at any amount of walking on them deforms the soft plastic at the slot thereby narrowing it, so a number of pullouts going up hills—fun!
We were talking about the need for using a somewhat deformable plastic so that the cleats wouldn’t crack while being bolted on, but there must be something better out there. Maybe something with a metal insert at the slot like I had back in the day?
