Tip 3: All genuine Adidas products have serial numbers on the tags affixed to them. The tags have the size and product information on the inside of the shoe (behind the tongue).

The fabric. The main point of difference between the Gazelle's and any other gym trainer is the fabric. The suede exterior keeps these trainers resolutely fashion-facing, and the large variety of colours, from understated monochromes to fun bright colour-clash options, keeps the Gazelle feeling fresh and modern.

OG – meaning original – is a reference to the shoe which was first introduced in 1968 and since that day its appearance has barely changed at all. Despite that, it has remained ever popular and is without a shadow of a doubt one of the brand's all-time best-selling designs.

But for most casual scenarios, both Adidas shoes work quite well. Unless it's raining. We found that the Gazelle is a bit slippery on wet surfaces but you probably wouldn't want to wear a suede shoe in the rain anyways.
