This year, I decided to make a giant stride, pardon the pun, and I bought Lawn Aerator Sandals by DBROTH on Amazon.com. (I'm reminded of Steve Carrell's scene in Crazy Stupid Love when he snuck onto his lawn one night to aerate is yard.) I figured aerating the lawn would help the lime and fertilizer get to the roots and I'd have a golf course quality lawn by mid-summer.
It didn't quite work out that way.
The Lawn Aerator Sandals, including full two inch spikes were extremely difficult to use. Balancing on the sandals before the spikes sunk into the yard was difficult. Frankly, I the sandals were a sprained ankle ready to happen. Worse yet, the straps would not stay tight, so every time I stepped, the sandals loosened. After every two or three steps, I'd have to tighten the straps. Eventually, I just did what any guy would do. I wrapped them with duct tape so they'd stay on my feet.
I only used the sandals once. I won't use them again. If you have bad soil you're trying to build into better soil, I wouldn't recommend these. Maybe Steve Carrell has a recommendation.
