I am writing this review after 3 months of purchase. I had purchased this product for my father.
After almost 2 months, the puff on the surface is gone. And the whole sandal has become very very hard and my father can hardly wear it.
I checked with the HP show room in, they said that this model is discontinued and hence they cannot help.
Not sure what do, looks like my money is waste. Never expected HP product too be soo bad.
