I got the 5.10 Canyoneers based on some others recommendations plus great experiences with their climbing shoes. My Canyoneers keep getting more and more use with hiking in to runs, boating in freezing or close to freezing temps, and more frequent creeking than ever before. In the 4 seasons I've had them, they only have suffered minor cosmetic damage and no issues with actual functional use. I have a pair of the 5.10 Water Tennies as well, and while I've only had them for just under a year and not nearly as much wear and tear as my Canyoneers, I haven't experienced any of the reported problems others are having.
I am pretty loyal to my 5.10s due to my experiences; however, if I was looking to switch footwear I'd probably go with Astral. I think it's great Philip from Astral took the time to personally reply, and I do love my Astral GJ. I think it's great that Astral is give boaters better options in footwear. While it is unfortunate people have experienced issues with product lines in the past, it does sound like it's a small percentage, if Philip is to be believed. I wonder if the people who have had issues with the 5.10s may be in a similar situation. Either way, it sounds like a good product change with the stitching of the soles, and may also spur competitive change as well from other companies.
