Navy Espadrille Grasshoppers by Keds

Navy Espadrille Grasshoppers by Keds women's sneaker. Wedge heel is about 1.5." It is shown where it seems that the glue has somehow turned darker over time and it looks like something spilled on them but, it's the glue used to hold the fabric. Haven't been bold enough to fix for fear of either making it worse or something. Shoes are super cute and I wore them despite their cosmetic error.
