What kind of sole is the 'Vibram sole' mentioned in the description?

Reading through the description, an unfamiliar name pops out not from the outer material or color, but from the sole. Vibram. To someone picking out clothes, it might be an unfamiliar word.

Vibram is not a shoe brand, but the name of an Italian company that makes shoe soles. The place where it made a name for itself was not the city, but the mountains. Starting from the rubber soles of hiking boots that step on wet rocks and soft soil, it is now widely used on shoes where traction is crucial, such as work boots and trekking shoes, and the yellow octagonal logo stamped on the bottom of the sole indicates that it is a sole made by that company.

What is used on the vibram mesh maryjane is the NEWFLEX sole, and whether you choose black or white, the same sole is attached^[1][2]. The role the brand speaks of for this sole is 2 things: cushioning when walking, and slip prevention^[3].

hmmm, the properties needed in the mountains and those needed in the city overlap much more than one might think. Painted road markings at crosswalks on rainy days or smoothly worn subway stairs are not that different from rocks when it comes to being places where feet can slip.
