The product described below is mainly for wet walking caves where a caver might prefer the standard industrial rubber boot.
Have you seen or worn the molded croc-style sandals, that are popular with kids ? A company has an industrial boot made out of this molded material. It has a nice lug sole, but I bet the sole would wear down after a few trips. The boots are almost as light as a pair of gloves. They are made in USA. They are about twice the price of rubber boots. There is an integrated plastic safety-toe sandwiched inside the molding. For more info go to: www.billybootsusa.com Disclaimer: I doubt my big foot would fit in their largest size. One idea would be to let all tourist wear these on the cave tours just for the fun of it. My theory is these could be worn with a thinner pair of socks than a standard industrial rubber boot, as the material seems to be soft and flexible. However, they appear to offer no ankle support, so a caver might want to wrap their ankles like athletes do with sport tape. David Locklear
