I think the 5.10 canyoneers are the best full boot on the market considering how good the traction of the rubber is. I've used mine last season and was very happy with them. Major improvement from a series of weak shoes that I looked at that were made by boating companies.
Canyoneers have a beefy sole which is great for scrambling on sharp rocks. The rubber stickiness on wet rock is top notch. You can friction climb up slick smooth wet rock. Got good ankle protection too. All around great boot.
The downsides of the canyoneer are the size. They can be hard to fit in a boat depending on foot size and bow space. Also, 5.10 will tell you to order a size up. The boots run a tad small, and when you wear them with a wool socks and drysuit bootie you need a bit more room. I normally wear an 11, but got a size 12 in the canyoneers. In hindsight, I wish I had the 11.5's. They would be a bit smaller in the boat, and I could likely fit in them fine. I have a nick of extra room in the 12s. My take would be order a 1/2 size up.
I had to trim off some bulkhead parts to fit the 12's in a large nomad. They fit fine in a jefe grande with no modification. They also fit ok in prijon boats with no center pillar. Suspect they would be fine in the big jackson creekers too.
You are more than welcome to try on / check out my size 12's if you want. Don't think anyone in the area carries them that I know of. I ordered off the internet. I rented a pair to hike the zion narrows several years ago and was blown away by how much they helped scrambling on wet river rock for 16 miles.
Also, I'd consider the savant too. Its the same sole as the canyoneer but more like a tennis shoe, without the upper.
People laugh when the see the "clown shoes", but that generally subsides when they see how well they stick on wet rock.
