These slippers are built like a good quality Italian shoe meets American work boots meets Training shoes meets Comfy pillows.
The sole is a solid block of supple rubber. The Leather upper has Velcro straps on both sides to allow your feet comfort even when swollen. Hard to find slippers for wide feet. But with OrthoFeet my 8 1/2 2E are the only slippers I can say I've ever enjoyed.
