The inner is TF Premium. I am using the genuine inner belt (3,300 yen). Used about 20 times. The inner has been heat-molded twice. Insoles are not included. There is some wear on the outer tongue from the shoelaces (see photos 7 and 8), and some discoloration on the right heel (see photo 9), but the EDGE's flex strength is still present. However, please consider purchasing this item as a used item with aging. Thank you for looking.
