Ashlyn Harris's and Ali Krieger's Must Haves: From Adidas Sneakers to Ultra-Luxe Coffee

For Krieger, it's all about carbonation. While she does drink "normal water" during training, "I have to have sparkling water throughout the day," she admits. And then later at night, if there's a game, "I'll obviously add some electrolytes to it, but I just have to have sparkling water over still water." Her fave is Original Perrier ($6 for four bottles), but she'll also allow La Croix. "We have a subscription for both," she laughs.

Pro Tip: Studies show carbonated water actually helps with digestion by encouraging more swallowing which reduces constipation. Something to consider next time a waiter asks, "Sparking or still?"
