I don't dive very deep, usually about 10m, and these ones take me down as fast as the full length plastic fins I used before. Plus with these it's easier to swim on the surface and easier to transport.

These fins are great. I went with the medium stiffness glass fibre version. So much easier to use on boats than their longer counterparts. These will be my workhorse fins for a long time hopefully. Would like to try the stiffer version too though.
