So in summary, these earpads totally ruin the overall sound quality of the m50xs but increase the comfort factor, and for the m30xs, they 100% increase the comfort factor and increase the sound clarity a little, for me at least. 2) insert mounting ring into rear of the brainwave earpad, this will be a struggle. I expect better from a higher-end brand like Keen. The material is more felt-like than suede and they’re probably not as substantial as the “real” shoes. For this reason I dont recommend it. Works great for my toddler. It is not as well made and seems to be thinner than the 24". These particular style of shoe by Vince Camuto are very tight fitting. Keep them clean, and they retain their grip. Sadly, however, what I received was a piece of cheap rubber cut into the shape of a narrow foot that is not up to size and cheap straps that tighten too.
