EnvyGreen Lawn Aerator Shoes

These are spiked sandals for a lawn. Strap them over a regular pair of boots, walk around the yard, and the 2.1-inch spikes punch holes in the soil with every step. That’s the point of aerating: the holes help water drain in, let oxygen and fertilizer reach the roots, and loosen up packed dirt. Usually it means renting a machine or paying someone. Here it means a long walk.

They arrive fully assembled, so there’s nothing to bolt together. An X-shaped strap with hook-and-loop fasteners holds the boot snug on the spiked base so it doesn’t slide around, and once the straps are set they don’t need adjusting every time. One size fits nearly every foot. EnvyGreen backs them with a full refund within a year if the results disappoint.

Give them to the dad who mows in neat stripes, knows the name of his grass seed and keeps an eye on the neighbor’s yard. He’ll look a little silly out there, and that’s part of the fun of giving them.

The catch: it’s all leg power, so a big yard means a lot of steps. And with spikes that long underneath, they come off at the door, never inside the house or on a wood deck.
