My Diadoras with mesh tops, from around 1984......with slotted cleats.
I remember mail ordering them from PBS when they were just located in Chapel Hill, NC...
I wanted to get Sidis or Duegis but I could not afford those brands back then. I think I got these on end of season sale.
I retired these after I got Look ipless pedals so I had to get different cycling shoes with the Delta cleat bolt holes.
Dug them up recently from my brother's attic in Glendale WI, where I left them back in 1990, when I moved to CA.
Surprisingly, they still fit me!
