Nike has officially unveiled the Adventure Club, which is a new subscription service that allows parents to swap out their kids Nike or Converse shoes for new ones as their feet grow.

This is the first of its kind, and it serves kids through sizes 4C to 7Y. (That’s roughly from age 2 to 10.). You can choose from three tiers of subscription services, ranging from four pairs a year to 12 pairs a year. You’re free to upgrade, downgrade or pause your subscription at any time. There are more than 100 different sneaker styles, ranging across the spectrum of performance and sportswear.

If you like the shoe, you can keep the pair. If you’re ready to replace it, send it back and Adventure Club will send the next pair of your choosing. Nike Adventure Club will either donate or recycle the returned sneaker.

The service kicks off on August 12th, but parents can sign up for the Nike Adventure Club here.
