A sneakerhead who made nearly $7 million in sales last year reveals the kinds of sneakers that are most worth the investment

1. Collaborations are key

A sneaker becomes more valuable if it is the result of a collaboration with a celebrity or athlete, Shams said. Examples of popular sneaker collaborations include those with Travis Scott, Drake, and Kanye West.

"I always tell people to always buy collaboration shoes because they're less likely to be restocked," Shams said. "Because as soon as a product gets restocked, the value of the item goes back down because now there's more sneakers in circulation."

2. Right now, Nike and Off-White's collaboration is huge

Nike and Off-White have collaborated in the past. Shams told Business Insider that this is one collaboration to look out for.

He explained that although the collaboration sneakers were not selling for much on StockX right away, they were still worth the investment because of the hyped-up nature of the collaboration.

3. Air Jordans are not always a safe bet

Rare pairs of Air Jordans have resold for as high as $20,000.

Still, Shams warns against blindly investing in Air Jordans without checking the production rate.

"Jordans are getting mass-produced to a point where not all Jordans are resellable like how it used to be," Shams said, adding that other pairs of would-be best-sellers that might not be worth the money.
