Decide if you can wear that boot every day. Is your style such that it would look at home with your clothes? It's a pretty expensive boot for an 18 year old if you'd only be wearing it a couple of times a week. I'll admit here that I'm generally against the idea of designer boots so I do have a bias. For the same price you could get this boot from Alden and I think you'd have better construction and access to Alden's recrafting service. It's a boot that would last you more than a decade.
I'm ok with designers for clothes for the most part and I understand the markup on them, but with shoes and boots I think money is best spent with shoe and boot makers proper.
