This is a Hydro fin's Tech II LEFT FIN, in size men's 9-10. This is for one fin only, the left foot, in size men's 9-10. The heel strap is rubbery and flexible and does not have any cracks, lots of life remaining.
I had this around as an extra fin to use in a pinch in case one of my main ones got sucked off , I got different new ones and just don't really see needing it anymore. This is good for anybody who lost a left fin and has a size 9-10 foot.
