It looks like Nike is nudging to get people to the 12 pairs a year subscription. Considering the time and energy saved + convenience can worth a $50 if you don't live near any shops. I think it'll be best for the parents with multiple kids.

The donations/recycling part gets good graces from me :) But I'm starting to think if this would all make shopping for shoes a less organic experience. I mean the shipping takes time. It's not teleported to you.
