Having sailed a Musto skiff now for some years, I have found the the best wet suit boots tend to be flexible, thin soled with high levels of grip and split toe. This gives a feeling of security as your feet don't slip on the deck unexpectedly and and you get better feed back through your feet with a thin sole. The draw back has always been the wear rate, at best I would get about 10 weeks of use before they fell apart. I have tried numerous types and makes of this type of boot and have now found the Rooster Split Toe Boot. This boot ticks all the boxes, lightweight, flexible, warm, very very grippy and they last much longer than any other similar boot. I would strongly recommend these boots for any none hiking boat.
