Walmart sells spiky shoes for like $27! They clip onto your shoes and you just walk all over your lawn: https://www.walmart.com/ip/20182202459?sid=A97B90BC-E09C-4776-8653-BCC3AD46B881 These are great for smaller areas and for homes without a lot of storage space. We use them for our little backyard lawn and it works. Though renting a tiller when it’s THIS compacted might be a quicker and easier way to go. Then use spiky shoes as maintenance aeration.
