Charcoal Knit Synthetic walking shoe by Vionic. Size 11M. Worn only 3 times. Very light. Flexible and grippy tread. Sock-fit-collar walking style is comfortable. Only reason I am selling is because the laces hit my very high arch in an odd place that is uncomfortable. If you don't have a high arch these would be amazing. Sad to see them go but need to get something different. These are gray with a mint green sole.
