Are Nike Pro leggings and tights the same thing?

[JMSA]

Just that really. Want to buy my niece a pair of Nike Pro leggings, but some websites call them tights instead. Is it just the same thing?

Yes, I have several pairs of ‘running tights’ which are leggings.

Not sure I always buy my DD Nike pro shorts and leggings from JD Sports

Check out their description

Yes same thing, leggings tend to be marketed for yoga, training and are called tights for running athletes.

I've never physically seen a difference.
