Is it safe or unsafe to climb an unsecured ladder that has slip-resistant feet?

Unsafe

Explanation:

This is not safe, but dangerous because without non-slip feet on the stairs, the friction between the shoes and the floor may become weak and you may slip and fall, especially if the stairs are wet. Maintenance-free stair slip accidents are common and can cause serious damage to people's health and mobility, in some cases this can cause serious fractures and even death.
