Versatile road-to-trail, but struggles on wet, technical downhills.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
I had the same problem. Merrell do a wide toe with a stack. They weren’t as wide as my Lone Peaks but wide enough
I actually have those Merrels in blue. I love them.
I wouldn't know haha. I have some wide feet and have no problems. About 100 miles of trails and they look like they are brand new besides mud stains.
Just came back from Val Gardena area (Col Rodella/Antermoia/Vajolet Towers). I used my Merrill Trail runners but packed a pair of black Rothy Mary Janes for pre and post in Munich and Innsbruck. They pack up flat, go anywhere and are comfy for walking. Highly recommend if it's not too late!
Very cool shoe that is hard to find, especially the original blue colorway. Solid waterproof choice though.
AP5 rip through the lace eyelets for a lot of people, including myself. Otherwise a solid tall shoe.
How did the minimal cushioning treat you on those distances? I got the adapt to supplement the longski’s, just assuming I’d need more support for a 100 miler. I did my Friday 100 in AGP5 and they were great aside from stability concerns.
Speaking broadly of the brand, I kind of wrote off Merrell for a long time before the the AP5's came on my radar when they started clearing them out this fall. For those who don't know, Merrell and Saucony are both owned by Wolverine brands and it seems like Wolverine is struggling a bit with their trail running strategy. Saucony expanded their trail presence a few years ago with models like the Endorphin Edge and Endorphin Rift, but has aggressively pulled back from that and now have only three non-budget trail shoes (Peregrine, Xodus Ultra, Ride TR) in their lineup. I bring this up because I'd heard rumors that Wolverine didn't think Saucony would focus on trail when Merrell was their "trail" brand. So far I've not seen any evidence that Merrell is increasing their trail running line or expanding into higher end trail super-shoes. It doesn't seem like Merrell gets much/any shared tech from Saucony so while the world moves forward with better foams it seems like Merrell is kind of staying put? I bought the AP5 this fall when they went on sale and came onto my radar. I've only got \~40 miles on my first pair, but once they broke in after 15-20mi and the mid-sole softened up they've been pretty great. The Vibram outstole is as good as anything and the rest of the shoe seems fine (although I have concerns about the thin tongue). I wouldn't hesitate to try the AP6, but at MSRP they've got a lot of competition with models like the Hoka Speedgoat 7, Saucony Xodus Ultra 4, etc.
IMO, I'd avoid expensive supershoes for hiking as a general rule. They tend to make a lot of compromises in comfort and durability and cost a lot more. A pair of Cascadia's, Speedgoats, Peregrines, Agility Peaks, Zagamas, etc. are going to probably be a much better choice.
