Product Name: Shunkan Spotto Size: 4L (26.0-26.5cm) - Color: Black - Design: Slip-in style - Sole: Synthetic sole (EVA resin) - Material: 100% Polyester - Usage: Outdoor Thank you for viewing. Only tried on, never used. I bought these for post-surgery use, but I didn't need them because I could use my regular indoor shoes. They are wide, so they might be good for people with swollen feet. Please consider them. I purchased them for 7590 yen (tax included). An inquiry postcard valid until the end of August 2026 is also included.
