Happiness with the NRS attack shoe depends on type of use. If you use them on a raft and you mainly walk on sandy beaches and don't scout / portage on wet rocks you might like them.
If you use them on difficult runs where you have to portage your kayak on slippery wet rocks you will likely hate them. I had a pair and I thought they sucked. The traction on wet rock was piss poor. The ankle protection was weak, and the sole didn't really have that much protection from sharp rocks either.
Also, booties are not made for warmth... if you want warmth, get a dry suit, dry socks, or neoprene socks. All neoprene booties will be pretty cold in cold water / weather with no extra insulation in my mind.
The new boot torch noted is called the gradient. Saw it in kayak session as well. Sounds interesting. They bill it as a climbing rubber sole with a lean bootie to be able to fit into kayaks. Only downside I saw was the big loops of laces that look like they are begging to get caught on bulkhead screws.
