How did they work out for you?
I bought some Merrell Moab ll mid/GT as a summer Boot with ankle support a few weeks back.
Unfortunately under real life conditions, the ankle support is only just about adequate ( I have a weak left ankle due to rolling over on it last year and tearing 2 ligaments).
They are fine for dog walking in the woods and light hiking, but for the rougher/uneven stuff I’m using my much more supportive Technical Torena GTX I got from Decathalon.
I guess the Merrell’s needed one more eyelet and I didn’t realize it at the time of purchase.

Thanks for the bump. They're pretty good for an impulse buy, I have to say. I plan to keep them. The support and traction should work very well for walks through our nearby woods, and also on rainy/snowy days when I need to walk to work.

Without the store-bought orthotics they fit very well and are comfortable. With them it's a bit snug, especially in the late afternoon. I imagine with prescription orthotics it would be the same.

It's hard to get accustomed to so much ankle support though.

Good for you. As for ankle support, the Moab is a mid model, you'll enjoy the support on slippery ground and long hikes. If you are enjoying this now in summer, think of the advantage in winter.
