2) hose them off! The top part if the shoes is very tight! These were a great buy! I was in the market for a larger portable speaker for parties and was originally going to get the Aiwa Exos-9 but after watching Oluvs Gadgets comparison of the two speakers on Youtube I opted for the Partbox100 since it went slightly louder and had a deeper and more powerful low end. fits well in the one size up. Good and solid. I expected this to last longer than a couple of months before it cracked for no reason. They were hard to move in and out during assembly and during deployment. Love these shoes so much, bought in all 3 colors. As an Added Bonus.
