With 2016 behind them, the pros are ready to start the 2017 season with new goals, with some of them kicking things off with new looks.

World No. 49 Fabio Fognini announced that he will be outfitted by Hydrogen, while also switching to Asics shoes. The Italian was previously kitted by Adidas.

Kei Nishikori, who is known to hold lucrative sponsorships thanks to being the highest ranked Asian player ever, was spotted in Nike shoes after almost a decade playing in Adidas.

He's still very much a part of the Uniqlo family (alongside Novak Djokovic).

On Friday, Nishikori will be tying up his Nike sneakers to battle wildcard Jordan Thompson for a spot in the Brisbane semifinals.
