Cold entry and exit

A strap at the top of the leg
is all that my Chota’s have and I have worn them for rescue practices many times. My socks have always stayed dry in them. There is no water coming in and they do not fall off your feet during rescues or even just swimming.

Thanks to everyone for the replies
and the advice. I agree that there is more too it than my simple questions. I especially appreciate the thoughts about spring water being colder and the links to other articles. My main objective is to extend my experiences to get more use and fun out of my kayak.

Cheers!
