Hi There, had my brand new mono in the water for the first time ever today and exactly the same thing happened to me, feet cramped after about 15 mins the foot pockets are a little large 'so i have neoprene socks (gonna try the bags now though thanks for that Evita!) and towards the end of my finning it felt like the mono was tilting to one side!!!! but Wow what fun it was... incredibly aquatic... I want more!
