Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
These are brilliant! both my children have had Chipmunks slippers for years so we've tested many pairs! Quality is excellent, your children will almost certainly outgrow these before the slippers themselves start to degrade. The fastening design is good and holds the slipper on the foot in the correct position, providing the necessary support to the ankle that children need. The backs don't break down and they're a snug fit, unlike other brands we've tried in the past which have elasticated backs for example that irritate the back of the heels or wobble on your child's foot. The soles are just the right thickness to be robust and protect the feet from anything nasty/sharp on the floor while remaining flexible for little feet to walk properly. They also have a good level of grip vs other slippers we've had in the past. The slippers also fare really well when put through the washing machine, we chuck ours in at least once every few weeks and they come out like new.
