My 'Empathy' sweatsuit is one of my favorites because of the bright colored font and the message behind it. He will miss at least the next few weeks of action. Built like a racer but designed for everyday training, these Flyknits are durable and good looking, too. The midsole, which provides cushioning, buffers feet from shock and largely determines a boot’s stiffness. Even as the city reopens, and setting foot in the subway feels just a little less unsafe, bikes are still lining the streets.
