Moon Shoes from National Geographic
These spaced-out shoes give kids a fascinating idea of what it's like to walk on the moon in semiweightlessness. Providing the sensation that gravity's pull has been reduced, they're ''wearable trampolines'' that let kids jump and bounce like the Apollo astronauts and hone their balance and coordination skills. Non-skid treads provide sure footing on all kinds of earthly terrain. Adjustable nylon straps create a snug fit.
