While I typically admire the whole DIY ethic, there are clear reasons why I do not make my own shirts and, especially, shoes -- both of which can often be had, for less than the raw materials involved -- not to mention those particular skills, of which I have little to no capacity. Leave it to those Chinese and Ulghur reeducation camps.
I swear by rock boots, which I use with either dry suits or wetsuits with neoprene socks. These particular ones are from Scubapro; but I have had other brands, similarly designed, which wore just as well. They are truly long-lasting; have an actual rigid sole and upper; and are generally in the US 90 -100.00 range.
It should also be mentioned that they managed to survive a glancing Torpedo ray strike in Pacific Grove, without any insult to my heel.
The pair in the photo, have been used commercially for about five years -- over thousands of dives; and the occasional wear and tear that I have experienced with them, can easily be solved by a modicum of patience and a cheap tube of neoprene cement . . .
