I cannot overemphasize the value of a good pair of shoes or boots.
This afternoon I put on an old pair of water shoes that I stole from my son. After working a bit just off the shoreline (getting ready to put in a new pier) I walked back to the house wondering why I had so much grit inside the shoes. A quick look found that the soles had cracked and started falling apart. Now I need a good pair of water shoes!
But seriously, I'm a person who struggles finding shoes & boots that work for me. The best I've found are Men’s Timberland PRO TITAN EH (Oxford) Soft Toe Work Shoes.
They also make taller versions - Timberland PRO TiTAN 6" Composite Toe - which I bought recently to keep chips out when chainsawing, but haven't used enough to comment.
