The quality is too bad, especially for summer sandals and spring and autumn shoes. On average, a pair can be worn for more than ten days. And don’t listen to those salespersons who promise that it is cowhide and that the cross-section will be broken in one month. It's all a lie. First of all, it's definitely not cowhide, especially for summer shoes. Secondly, the brand is not guaranteed nationwide and can only be handled at the store where you bought it. In addition, you will never be given any after-sales service. When you replace it, whether it breaks after only wearing it for a day or half a day, it would be good to patch it up for you. Finally, Yierkan headquarters has a bad service attitude and if there is a quality problem, the first thing is to distance itself from its own responsibilities and not provide solutions to customers! Therefore, this brand is going bankrupt and there will be no repeat customers! If you want to buy, buy the Spider King, or simply buy from the street stalls and wear it for a few days before replacing it with new ones. The price of Yierkang is not cheap, it is not genuine leather, and the after-sales service is even more insecure. I advise you to think twice!
