Rejoice, footie fans, because the World Cup is once again underway. The action opened on Thursday with Brazil defeating Croatia 3-1, and will continue throughout the next month until a champion is crowned. Brazil enters the Cup with a record 5 titles, while Spain will be looking to defend their 2010 win.

Fittingly, this week's Instagram roundup has a heavy World Cup focus. You'll find behind the scenes shots, sneak peaks at the latest cleats, and much more football action, as well as the rest of the week's best sneaker 'grams. This is This Week on Instagram: World Cup Fever.

"Once they’re on, she’s gone. Canadian 800m Champion Melissa Bishop hit the Nike Sport Research Lab hard. She wanted the 31st edition of her favorite shoe to be the fastest, lightest, and most responsive yet. So we got to work. We called on everyone from loyalists to skeptics to the elite—and delivered our fastest #nikepegasus yet"
