If I don't need booties (i.e. only warm water diving from a boat). I'm taking my Mares Superchannel full foots. They are much more powerful than my Go Sports yet about .5lb (250g) lighter per pair. They are also comfy on my wide feet although I did size up. I usually wear a Euro 43 and these are labeled 44-45 (9.5-10.5 US).
