Awesome old school pedals, I use to have a pair which I painted to match my frame color of a Trek 520 Touring bike. These do require the old style metal toe clips of which Campagnolo makes the best.
No these do not clip to your shoes, they require old school toe clips that are held on by screws to the pedal and require leather on nylon toe straps. Special shoes are not required to use these.
I forgot to add these require special toe clips which I believe are plastic but also have less of a tendancy of wearing holes in your shoes. link to Ebay auction for more info: http://www.ebay.com/itm/VINTAGE-SHIMANO-105-PD-1050-PEDALS-W-TOE-CLIPS-/310875118577?pt=US_Pedals&hash=item486199dbf1
