Like the slightly rough edge on these slippers 5 Stars
Buying slippers has never been so much fun as it is online. The choice is brilliant and you can select without being hassled by salespersons, also you can check the full specs.
This pair I bought for the bright colours and added bonus was the slightly terrain kind of feeling on the soles of my feet.
One thing you should remember - when buying rubber slippers, please buy one or half size smaller than your shoes.
AND PLEASE DO NOT DRIVE OR RIDE IN SLIPPERS IT IS NOT SAFE!!
