The Robot Casual Sneaker boasts a printed fabric upper and a soft fabric lining for superior comfort. It features a cushioned insole with arch support and a removable inner sole for personalized fit. The 4-eyelet lace-up design ensures a secure hold, complemented by a stitched, non-marking rubber sole for durability. Use the size chart to find your ideal fit; if your Mary Jane Flats fit well, select the same size for these sneakers. For a snug fit in flats, consider ordering one size larger, especially when wearing socks. Delivery typically takes 5-10 days.
