Collection: Black wool felt sole | Heiwa Slipper

The soles of the indoor slippers we produce are made of two main materials.One is made of vinyl soles. The other is made of wool felt soles.
If you compare the two slippers, the difference is obvious. Wool felt soles are clearly quieter and more comfortable than vinyl soles, which tend to make a clattering sound.

Why do we recommend in-house slippers with wool felt soles? | Heiwa Slipper
