Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
Great quality sneaker. I was a little sceptical of the size being correct as I couldn't find the size chart. I took a punt on it and was not disappointed! Great shoe and the sizing was correct sizing for a young child. For the price I thought it could potentially be for a toddler, I was surprised and I purchased another 2 more pairs.
