It has been fine for aerobics dvd's and cross training but today, when I ran for the first time in years, the seam on the strfap on the top of my shoulder rubbed so much that it nearly broke the skin. I had to wind the sleeve of my tshirt round it to stop it.
and I was only running for 10 minutes ffs!
Who puts a seam on the ONE part that will hit your skin?!
