I bought a fairly old pair of crampons on e-bay, and found that they won't fit me. They're made in Austria, the brand might be S&C. They're not adjustable, and they have the number 40 stamped on them; I presume that means the European boot size 40, which translates to size 7 men's or size 8 to 8 1/2 women's. They have leather straps which should work on most boots or trail running shoes. They are in pretty good condition, and are very sturdily made. Probably better for hiking and slope climbing rather than ice climbing.
I paid about $27.00 plus shipping for the crampons; I'll entertain offers of cash, trade, or services (take me along on a class 1-3 climb with pizza afterwards?).
