Before you buy anything
A few things worth knowing first
Don't buy a $300 tour racket. Frames used by Federer or Djokovic are stiff, heavy, and unforgiving — they punish off-center hits in a way that will make you hate tennis. Beginners need a 100+ square-inch head, modest weight (10-11 oz), and lots of forgiveness. The racket many pros endorse for beginners is not the racket they actually play with.
Borrow before you buy. Most public courts have a friendly regular happy to let you swing their racket for ten minutes between games. Even better, most pro shops at private clubs let you demo rackets for a small fee — a $5 demo is the best $5 a new player can spend.
Tennis shoes are different from running shoes — and the difference matters more than for almost any other sport. Tennis demands hard lateral planting and stopping. Running shoes have soft, tall heels designed for forward motion; they roll your ankle on a crossover step. We list this in the gear, but it bears front-loading: don't play tennis in running shoes.
