This is a trial set of 25cm size Ashiito R-type, K-type, O-type, and SUASI (for women). Each type includes one pair, for a total of four pairs. For those who want to buy Ashiito but are unsure which type to choose, or for those who want to try them out first, I hope to offer them at a reasonable price. Ashiito is a disposable paper insole designed for "deodorization," "sweat absorption," and "countermeasures against stuffiness in shoes." The wavy surface provides moderate stimulation to the foot's pressure points when worn. Because they are disposable, even those who work on their feet can wear clean shoes every day. They were an essential item when wearing pumps. Please understand that these are items stored at home, and consider purchasing them.
