An exhibition of exotic shoes is being held in Barcelona, Spain. Look, what a creative design. The theme of shoes is only part of this shoe show. The name of this strange shoe show is called "changing shoes". The shoes, which are designed by bullfight, are the same as the first two pairs of shoes. Shoes like these shoes may cause blisters on the feet of the wearers. Is this shoe very much like a sardine tin box? Such high-heeled shoes will be a great challenge to the balance ability of the wearers. The biggest advantage of this kind of shoe is that it eliminates the trouble of wearing shoes early in the morning to match socks. The heel of such a shoe is too avant-garde. These shoes look like they are designed for future trainers, or cavalry.
