Want to keep it aerodynamic in your lowest-profile sneakers? Then the Nova No Show might be your new BFF. Featuring a slightly higher heel cup with a soft, silicone-free grip, there’s no way this baby’s bunching up or sliding off. The extra cushy toe will help you avoid any blisters or pinch points. And the Space Dye yarn is so galactically cool, you might just ditch the shoes entirely.
