Thank you for viewing. This is the "STEEL BLUE" specification of the "M2002RFB," reminiscent of New Balance's masterpiece 1300J. I purchased it from the official online shop. I have worn it about 5 times when shopping in the nearby shopping district, and I use insoles that I purchased separately. I only wear it on sunny days, and there are no noticeable stains, but please refrain from purchasing if you are concerned. Model: 2002RFB Color: Steel Blue Material: Mesh/Suede Retail Price: 19,800 yen Accessories: Original box, instruction manual The following is the product description from the manufacturer: The 2002R is a reinterpretation of the popular technical running model from 2010, upgraded with modern performance based on the original design. This is not "retro." The mesh and suede overlay upper construction is finished with smooth curves and cutouts, adding a futuristic nuance to the classic look. The comfort and performance provided by the Stability Web, N-ergy shock-absorbing outsole, ABZORB midsole, and ABZORB SBS heel cushioning remain unchanged over time. Features ACTEVA LITE midsole cushioning is a versatile item that flexibly supports various situations. ABZORB SBS heel cushioning provides a sense of further stability and comfort. N-ergy outsole provides the best shock absorption. Stability Web outsole technology enhances arch support. Inspired by running shoe designs from the 2000s Pigskin/Mesh 360 grams (12.7 oz) Thank you.
