Thanks for the reply Mr. Leches. I was thinking about the powertrack liners, thanks for the advice. One more question then: sizing. I've got the TLT7s in 28.5. Which size Palau's should I get? And also, when heat molded, should they compress enough in the tight spots and expand enough in the loose spots? I don't have much extra space in the length or width of the boot; I'm mostly trying to suck up volume around the ankle, lower leg and on top of my instep. Thanks again.
