I mostly run in skorts & wear leggings for casual, occasionally I do wear to run in them if it’s particularly cold but in old fabric I had to use the chord as the waistband would drop.
However the new amazing fabric the chord is not necessary. The waistband feels higher and much more secure, I wore them a run just to test and they were absolutely brilliant they didn’t move at all. I had the pockets loaded with phone and with a bottle of water (just for testing purposes)
The colours in new fabric are so vibrant and while the other fabric were squat proof these just won’t white at all. They are amazing. Again I sized up as recommended and they are perfect.
