The winter sea is windy and cold, so how about using this for lure fishing, other types of fishing, or water work from the surf? I've converted a diving drysuit by cutting it from the air valve down and turning it into fishing waders. It's made of 5mm neoprene material for excellent heat retention. The foot size is 26cm, and the size is about M. See images 11 and 12 for the fit. I'm 168cm tall and weigh 58kg. I think it's a normal wader with foot. The ankles to the knees are made of radial material, which is durable. The shoes are 26cm, and it might be a bit tight if you wear thick socks. It has a good fit overall, and there's no looseness typical of waders, so you'll likely experience less ankle fatigue when walking long distances on the beach. The shoulder straps are made of rubber. They won't slip off even without them, so consider them a bonus. Thank you.
