In my experience as a craftsman, a 'fitted' strap is one that is shaped to perfectly follow the specific curvature of the watch lug. It is part of the Milano Straps method to achieve finishes consistent with the collectible level of our straps.

I use it at precise stages of the production cycle, combining it with manual checks and vintage tools to preserve the naturalness of the leather.

Just follow the instructions included with each strap: gentle cleaning, no direct heat, and rotation between multiple straps to allow the material to rest.
