You asked, we listened! The new 4" Cadence Short combines the ultra-lightweight comfort of our AFO woven fabric with a soft, high-rise waistband and longer coverage through the thigh and seat.

While they feel so light you might forget they're on, the Cadence Short is designed for the runner who wants to up their coverage game. The high-rise waistband is softer than our traditional AFO Middle Short waistband, for a smooth fit through the hip. The cut through the hip and thigh is generous for a comfortable fit, and the rear runs longer so you won't feel exposed on the trails or during post-run errands. Read more

W's 4" Cadence Short

Great shorts!

Exclusively bought this for an ultra fell race. I didn’t get a chance to have a “dress rehearsal”, but I had no problems wearing it on race day. The fabric is super light and the color is so vibrant. I used the back pocket to store the wrappers of my energy gel and it was easy to navigate. I wish I could buy more Janji shorts but they’re kind of pricey so I’m keeping an eye on sale promptions. Very many thanks to the amazing UK support team who replied quickly and did what they can to expedite delivery before we went away for the race weekend (I bought it late and on a whim, after reading great reviews—which didn’t disappoint)!

Great running shorts

Have worn these shorts on a few trail runs so far. Got them in the very cool blue print which I love! They're unbelievably comfy, the waistband is great. Really like the pocket in the waistband also, I find particularly useful for a shorter hill run where I only really need an emergency snack. I have easily fit some gels and a pair of gloves in the back pocket with no effect to the feel of the shorts. I would guess a very small soft flask would fit too. Such a lightweight and soft material with a bit of give. I like these shorts because they just give a little bit of extra coverage. My only gripe would be the lack of zipped key pocket, I do understand that there's a little key pocket internally at the front with a loop for secure attachment, but I just find it a slightly odd place to have my key pressed against me? Could be just what I'm used to though.
