AMBUSH Quilted Leather Slides

AMBUSH Leather Slides; black calf leather, quilted labeling, size 42 (9), mens. New, never worn. Fit: size is 42/9us mens but is pretty narrow. Maybe feels more like a 41/8us. It’s calf leather so might get some stretch eventually AMBUSH is a Japanese designer so maybe why the sizing runs smaller?? Authentic and bought from Saks Off5th
