If you want to to be the next Olympic gold medal winner like Michael Phelps, then get yourself a pair of the Speedo Hydralign Goggles ($15). They're training goggles that promote correct head position and body alignment with slanted lenses that are frosted on the lower half, causing swimmers to hold their head in the proper position to see.
It may be a little pricey for something you just kick around, but the Total 90 Aerow Soccer Ball ($120) has more features and went through more testing than most electronic gadgets. It was designed to "set new standards of speed, accuracy, and consistency in flight," and sports a unique visual design that makes it easier for players to react to the ball. "More than two years of research and design and 15 experimental prototypes went into the creation of the Total 90 Aerow. The ball was tested for over 100 hours in wind tunnels
at major universities. Repeated lab testing was
also conducted using Nike's special kicking
machine, nicknamed Bigfoot." Geez.
If you and your buddies hold late night ping pong battles and you need that extra bit of intimidation, or if you're a professional table tennis player with a camo fetish, this Ping Pong Paddle Cover ($65) from Jack Spade is just for you.
