Burton Ion Asian Fit Speed lacing type. Purchased used (used for 30 days) and used for about 10 days. The outer shell is still stiff and not worn out. The year of manufacture is unknown. The area under the laces on the right boot was peeling, so I applied a patch. There is a scratch on the back of the outer shell on the left boot. The right side of the inner boot on the left was peeling, so I attached a piece of cloth.
