All about the pull

The back pocket on all AFO style shorts features a nylon pull to allow for easier pocket access on the move.

Get geometric

Inspired by the refraction of shapes through water, this print was designed by Cape Town-based artist Al Luke and features his organic line-work style. We see an abstract landscape of explosive shapes in this print, like a picture into another world.

The AFO Split Short is designed to keep things fairly modest, as far as splits go, until you open it up in stride when the 5" side split allows for total unrestricted range of motion.

Lightweight and Super Comfy

I bought these shorts after purchasing some other Janji products that I love. I was thrilled to see that the outer shell of the shorts is made from really light weight and comfortable fabric. Like any Janji product, it was clear to see that these shorts were made well. It's the details like the breathable and firm waistband and the material chosen for the brief liner and pockets. About a week after getting these and doing a few shorter runs, I put them to the real test and wore them for a marathon. I was so thrilled to find I had zero chafing and felt comfortable for the whole run. In terms of size, things run a bit on the small side compared to other brands for me or rather have a true/snugger fit. I am 175cm (5'9") and 61kg (134lb) and got a size small. It fits me snugly in the waist which is what I prefer. I could have work a medium for a loser but still good fit as well.


Comfortable and looks pro

Love them!

Great running short, INCREDIBLY comfortable, I wish I had these in all colors because everyone compliments them and loves the patterns. Hopefully my friends will seek them out.

Great Short!

Lightweight, quick dry, drawstring closure, and pretty good support. The wide waist band is great..probably one best on the market. I like the artist design shorts. They are definitely one of the top running shorts/racing out thereHowever, they are a little on the pricey side.

Best running shorts I’ve bought

Love the pattern, love the lining, love the pockets, love the fabric...I’m resisting buying this short in every color ever.
