Watching a YT video from Yowana on version 4 before these arrived had me worried, even though it wasn't the same model, and after receiving these 3 SPW, my fear was confirmed... each midsole has a COMPLETELY DIFFERENT feel, with the right one being soft and pillowy, while the left one is MUCH firmer. It's like walking with two different shoes altogether... brick, cush, brick, cush, etc. It doesn't seem like something that would correct itself over time, since they'd both change, not just one. HOW DOES THIS HAPPEN? WHERE'S THE QC?
