Even though this is real tile, it's more a job for the laminate flooring guys than the tilers. For instance, floating tile works only for flooring and no other applications. Tub surrounds, shower pans, walls: those are all still jobs for conventionally-installed, mortared tile.
One common cause of hammertoe is related to wearing high-heeled style shoes or overly narrow shoes that crowd the toes. The muscles of the toes work in pairs in order to achieve straightening and bending movements of the joints in the toe.
Hammer toes often occur with bunions. Claw toe often affects the four smaller toes at the same time. The toes bend up at the joint where the toes and the foot meet. They bend down at the middle joints and at the joints nearest the tip of the toes. This causes the toes to curl down toward the floor. A mallet toe bends down at the joint closest to the tip of the toe.
