Not that I noticed.
When Merrell first came out with minimal shoes, I was disappointed because I found them all to be too narrow and I couldn't wear them. I've steered clear from Merrell shoes since than. My wife bought me a pair that were on sale years ago and I never wear them because they are narrow and not comfortable.
The All Out Drift boots are the first shoes by Merrell that I've tried on in a long time. I didn't notice the width so perhaps that's an indication that they are a bit wider than their "glove" line of shoes. They were certainly wide enough for my feet and often that is not the case. The few seconds I got to run in them, my toes were able to splay naturally and the boot felt secure but not tight.
