Hi and welcome!
Most people tie a series of knots in the top of the sock poi to give extra grip, anything from one to three in a row. Then just hold on. If you find your hands are becoming strained from gripping, you may find it helpful to wrap them aound your fingers. Also you may find the sock poi from here too strechy to do certain moves when you become more advanced. Good Luck!
