It extends onto the back of the t-shirt. Is it maybe a foot bone?

it says

“Reflective swoosh”

its an abstract nike swoosh

It looks like bones

I can see the abstract Nike Swoosh but the back looks like phalanges or a finger pointed at the spine perhaps???

The reflective swoosh is the one that is on the sleeve not the image that the OP is talking about (see the last photo on the Nike site).

Yes it’s the foot bones. The toe is round the side/back

It's specifically a running shirt - so I'm thinking maybe the bit on the back is a big toe...? But it's quite lumpy for foot bones.

but it’s in the shape of the nike swoosh

clearly

I reckon it’s like the Nike swoosh but also bones of foot in a running position-ish

It’s a Nike swish made up of bones

I think you're right @fourelementary - but that makes it upside down I think?

It could be if turn it clockwise 90’ a side view of a shoulder. Spine then side view of scapula and the round bit the head of humerus (mostly hidden by spine) but I don’t know why that would be on a running shirt.

it’s weird unless you’re into orthopaedics or feet
