The Aimeos Laravel package and the Aimeos shop distribution based on Laravel support now URL segments without sub-paths. Than means, you can have URLs like /sneakers, /nice-blue-top-sneaker and /contact as URLs for categories, products and CMS content pages.
All those top-level URLs are handled by the ResolveController, which checks if a category, product or CMS page with that URL segment exists. This feature isn't enabled by default because it requires additional database queries to check what type of entity is assigned to that URL segment. The README of the Aimeos shop distribution contains a section how to enable the multi-routing feature.
