I just took 20 pebbles out of holes in the bottom of each sole. I was really counting on a thick cushiony soul. I ordered the white and black set. The sizing does seem a bit off like the other reviews say. Es mi segundo par, el primero lo perdí y por el precio no me dolió reponerlos I buy this brand & style of QuiI absolutely LOVE this wine rack. I take these off when I go out of the bowling area because Ive had trouble in the past with my sliders picking up dirt or moisture then not working right until I put them through the laundry. Sound quality beats the AS10s and BA10s but the extra driver means the housing is not insignificantly larger and it just feels and looks obnoxious even in my fairly large ears. Works as expected! A+ for these guys - and over many years!
