MORGEN SKY Diving Boots 5mm Isogutsu (Rocky Shore Shoes) Sawa-gutsu (Stream Shoes) Keiryu (Mountain Stream) Neoprene Shoes Fishing YZ001 I purchased these and used them once yesterday for SUP fishing. The size was a bit too big, so I'm selling them. They feel a bit larger than usual. The MORGEN SKY size chart says US 12 is 28cm, but it feels like it's more like 29cm or larger.
