[About 3cm difference] The competition for this style is too high. While competing, many fake sellers have lowered quality standards. We always prioritize quality and price for cost performance, original creation, seasonal new styles, gaining popularity at a loss, limited quantity. [About Material and Properties] This style is a loss-making attempt aimed at five-star reviews! [About Size] For those with wider or fatter feet, we personally recommend purchasing one size larger.
