I saw Jordan Fly Wade Orion Blue on sale-kicks.com. I really love it, is this shop legit to buy?

I see that you and all the other answerers are Chinese. If you are in China and don't mind buying illegal fakes that are badly made, this is the site for you. If you want real Jordans, go elsewhere. I hate to say this, but many of these Chinese sites are run by thieves who steal your money and your identity. At worst they sell you illegal fakes of brand names that are very low quality and overpriced for what they are. If the item is crossing any borders, it can be opened at customs and will be seized as illegal goods and destroyed, plus you get a big fine for engaging in criminal activity.
