Who says good looks and smarts have to be mutually exclusive? Puma built the Voltaic with the opposite in mind: it’s a functional gym shoe packed with tech-savvy cushioning, breathable mesh, and a grippy outsole. Buy it for $38.40 (Reg $80) as part of the Puma Semi-annual sale where you’ll save an extra 20% on all sale items. Shipping is free on orders over $75. Otherwise, it’ll add $7. Extra savings end 7/7.
