Many top WTA names took to Instagram to celebrate Nike Air Max Day earlier this week. Sloane Stephens, who is sponsored by the athletic-wear brand, was feeling nostalgic in her pair of Air Maxes. Meanwhile, fellow Nike women, Simona Halep, Victoria Azarenka, Petra Kvitova and Elina Svitolina shared their favorite styles of the iconic shoe. 

"This one is an oldie but a goodie reminding me of how far I’ve come and can keep going," the 2017 US Open champion wrote on Instagram. 

These are the best looks of the week:
