It didn't take long.
3 pair of waterproof boots DE-WATERPROOFED.
The pair I bought for $30 at Walmart I think may have naturally wore through the heels in one month on the pavement.
But the other two were definitely vandalized.
So we have:
- Worn out in one month
- Sole separated from boot - NOT natural
- Heels shaved off with emery wheel - NOT natural
