ABSOLUTELY FANTASTIC! SHOE 💯❤️
Very stylish canvas design with that Polo flare & logo.. I dressed these up casually with a midi skirt & top & down with denim Capri pants and a cute top and multiple times these sneakers never disappointed.. Im a women's sz 9-10 and ordered both sz 8 & 8.5 too make sure the fit was comfortable and they are a true sz fit for a women's sz 9 & 9.5/10. They're easy to slide into, cost is budget friendly and shipping/delivery was super fast. I highly recommend these sneakers if you're looking to step out jazzy casual 🫶🏿❤️ I'm really happy with my purchase I had to order more😁... Seller is⭐️⭐️⭐️⭐️⭐️Highly Recommended Thank you kindly 🌹

Very good looking shoes
Size: 11, Color: Black/Black
I really like the way these shoes look. They look different yet “well known”, as in, these are regular flat shoes but with a very unique design that make them seem neat and “basic” yet different and stylish. I personally loved them. However, I don’t really understand how so many reviews call these “comfortable”. They are very well made, yes. These definitely promise to last. On the other hand; the fabric feels rather sturdy or rigid. They fit perfectly. For me personally, I have rather narrow feet and these may feel a tad loose, which does not help at all. My feet feel sore after walking on them for some hours and also they feel rather heavy too? I mean, these shoes are inexplicably heavy. Either way 10/10 in style 6/10 comfort
