Buckle Shoes

I want a pair of buckle shoes. After seeing ones on the feet of salesperson at luxury shopping complex, i was hooked! I am trying to get one here as I don't know the word when i searched them on ebay... has anyone known or seen where can i get one? please please contact me!

PS. i know one of them is Gucci's but you know i'll never buy leather shoes from Gucci, never.
