Just Bounce Inc., Wellington

Pounding the pavement feels more like walking on air when you're wearing Kangoo Jumps. The gym-sneaker alternatives sport pliable ovals beneath each shoe's sole, which ease impact on joints and makes wearers as buoyant as as a politician full of hot air. At Just Bounce Inc., every class attendee dons a pair before diving into a high-intensity, low-impact fitness class that can include arm work with hand weights.
