Yorkers can also be aimed directly at the batsman's feet, forcing the batsman to shift his feet while attempting to play the ball, or risk being hit. Inswinging yorkers have a reputation for being particularly hard to defend and difficult to score runs off. Such a delivery is colloquially known as a sandshoe crusher, toe crusher, cobbler's delight or nail breaker. A recent variation is the wide yorker, which is delivered wide of the batsman on the off side. This is particularly useful in Twenty20 cricket as a ploy to restrict runs rather than to get the batsman out.
