As any sneaker fan (even a casual one) will tell you, New Balance 990 sneakers may go down as one of the most popular styles of this decade, and for good reason. The

streamlined, slightly retro gray sneakers make any outfit look cooler, and they're about as comfortable as sneakers get. And even though it's seemed like everyone has had them for the past couple of years, they're hard to get tired of.

The only downside of New Balance 990s is that not everyone is eager to spend $185 on sneakers—even if they are worth it—and some people like a little more color in their sneakers. One of those people seems to be Hailey Bieber, who often wears colorful sneakers. She recently opted for another classic style to pair with her leggings and fleece: New Balance 574 sneakers. They come in a variety of color combinations, and they retail for $85 full price. (Although, I found plenty of on-sale pairs.)
