Puma x Fenty Pink leather bow creeper

Puma x Fenty rare discontinued creeper sandals. statement piece, feminine and comfy. size 7 they are really in great condition. they were used a handful of times, as you can see the soles are still intact. no scuffs but right sandal has a stain on the front right side (see pics) I'm not sure what is or if it could be removed.
