If you're not that into sneaker design, the Adidas Gazelle might look pretty much the same as the Samba. And that's somewhat true, but there are some subtle differences that give them a unique edge. For instance, the Gazelle comes with a full suede look, a slightly taller midsole, and a longer tongue.
Another difference is that Adidas Samba sneakers usually feature a distinct rubber gum sole with a brown or tan shade that really pops against the rest of the shoe. On the flip side, the Gazelle kicks typically come with a normal rubber sole, but you can also get them with a gum sole if you go for the Indoor version.
