Long (10") ...for regular length pants worn above your ankle (like 501's, Straight Legs, or Dickies) with boots or shoes with a heel.

Medium (9") ... for longer or wider pants (like Boot Cut, Baggies, Wide leg, or Bell Bottoms) with boots, sneakers or low heel shoes.

Shorties (8") ... narrow and a better fit for riders with long pants with a low heel. Great for chaps or rain pants that cover the whole heel while you are riding.

Xtra Shorties (6.5") ... Xtra narrow for riders with super bell bottom pants with low cowboy style heels. Work great for Lady riders wearing higher, stiletto type heels.
