Lawn Spike Shoes
This would be a good product if they would stay on your feet. Unfortunately, the straps make a very poor connection to your shoe. As such, they come off after every one or two steps. After a while, they are just put on the shelf and not used.

good for the price
Be careful when tightening the straps, the plastic buckle will break if you pull to hard on it. Once the straps are correctly threaded the shoes never came off my feet. I was even able to use one of the shoes with only one strap (the rear strap), will probably fix the other strap with velcro so it doesn't flop around.

works ok
it works preety good. they are sharp spikes on the end so it goes in nicely

Aerator shoes only for small area.
They work as advertised, no more, no less. Not really very useful. I didn't expect much, so I'm not disappointed. Would be effective for a small yard.

disa-point-ing
I was disappointed with these spike shoes, even though they weren't very expensive. The straps did not secure the shoes very well over my shoes, even when I adjusted them properly. I pulled one of the straps tighly and the plastic nylon buckle snapped. Bottom line, when I did get them to fit and stay attached, I had to walk very carefully to avoid them falling off completely. The average person is not going to want to deal with it. The spikes are very strong and do a good job of aerating whatever you do managed to step on. If they improved the strap system and they stayed on your feet, I'd pay MORE for a product like this.
