Purchased at the New Balance Ginza store in early August. Used about 5 times (tag cut). The technology cultivated through running is now available for everyday wear. Pursuing ultimate ease of movement, comfort, and fit. 4-way stretch with punching provides excellent breathability and lightness. Length is 40cm from the top of the waistband to the hem. I don't know the model number, but it's a new model as it was in the store.
