Force Fins: Size L – $100 $75 These Force Fins are in excellent condition. If they are worn over the neoprene boot of stockingfoot waders (or over neoprene socks), they should fit anyone who wears a (U.S.) shoe size ranging from (women's size 7) to (men's size 9). However, they must be tried on (over whatever you will be wearing when using them) in order to ensure a proper fit. RRohrbeck@comcast.net. $100, $75.
