I was always under the impression that Sambas and Tigers were "the" shoes for toeclips because of the sole...stiff, yes, but also they don't stick out and climb up the side of the shoe like, say, Vans or Chuck Taylors do. I always find Vans and Chucks awful for clips because the soles crack pretty early on as they get broken in, right around where the shoes bend as you walk. That crack always interferes with getting in/out of clips.
