I think you're right. It's like the textile concept of woven vs. knit fabrics. Woven (non-stretchable) fabric holds colors better because they don't stretch (this is how suits are made), whereas knits do stretch, making colors fade faster as a result.You wouldn’t want to go for a forty-five minute road training jog in racing spikes but when the day of the meet comes you can’t race in sneakers.
It doesn’t mean the racing spike needs more cushioning and upper and ankle support.
Also I’m starting to wonder if a color like Capri or any of the rich ones that make a silicone phone case aren’t workable on a solo loop because they can’t keep the color when they stretch.
