Does Kicks on Fire sell authentic shoes?

Hello there, I've been eyeing a pair of sneakers on Kicks on Fire and I'm wondering, does this platform guarantee that the shoes they sell are authentic? I've heard some mixed reviews and I want to make sure I'm not wasting my money on fakes. Can you tell me more about their authenticity policy and if there's any way to verify the authenticity of the shoes before making a purchase? Thanks in advance for your help!
