I had already pointed out that this was not suitable for the elderly as too soft, the fabric of the mule distends and therefore the foot can turn into the slipper and one can easily stumble. I come back to report that I bought this pair in December, and there end of May, so nearly 6 months later, slippers has a pretty big hole in the insole heel side and the other is at the forefront of disjointed Foot: slipper so yawns in front. This is the first time a product isotoner disappoints me so much. I think a pair of slippers should last at least a year, if not two.
