Super comfortable from the first wear! Unique soles
Size: 10, Color: White Khaki
My husband actually picked these shoes out and bought them for me without my knowledge for a vacation we were going on. When I discovered he had bought me some sandals I assumed they would likely be super uncomfortable, too narrow, weird looking etc lol. I definitely didn’t give him enough credit. I absolutely love these shoes! They are incredibly comfortable! They match pretty much everything. The bow at the toes is so cute! The soles are a very cool sturdy and hard almost wood like material, while also feeling like a dream to wear. I ended up wearing them with my bathing suits, my shorts, my sundresses and even a couple of dressy outfits! I pretty much kept them on the whole vacation and ignored the 10 other pairs I wasted time and space packing. I don’t know what it is with these shoes but even o. Days we were walking really long distances at the beach or on days I was running all over the cruise boat from dusk til dawn, I never once felt uncomfortable in these and felt just the opposite in fact. I often get achey feet too; but it didn’t happen with these. Whether I was strolling the deck, dancing in the club, or standing waiting in long buffet lines, these shoes had me feeling fancy free and footloose.

The best sandals EVER
Size: 8, Color: White Khaki
These flip flops are so so so comfortable. I have bunions and a nerve problems so finding the right shoe is an issue for me. These are the most comfortable flip flops I have ever had the pleasure to wear. I cannot recommend enough how good and natural these feel. They are flexible yet supportive. So far on vacation they have walked miles with me and still in great condition. They are so naturally light weight. I will be buying again for sure

Most comfortable flip flops ever! From day 1!
Size: 7.5, Color: White Khaki
These are hands down the most comfortable flip flops ever. There is no 'break-in' period. The fabric is so soft you forget it's there and it doesn't rub between your toes at all. By the second full day of wear, the foam was starting to conform to the contour of my feet. They feel and look great. The bottoms have a nice triangle tread pattern on them instead of being totally flat so I'm hoping they will still get traction on wet floors like pool areas etc. I got them after nearly doing a split again in my old ones that were a safety hazard poolside.

Nice flip flops
Size: 7, Color: Grey
Nice looking flip flops. They feel good and well made, but I've only worn them for a few hours. The material that goes over the feet is almost too stretchy. I hope they don't stretch out more. I have wide feet and these fit great, true to size. I like the grey color.

Love the material!
Size: Large, Color: Black
Very soft and beautiful material. The size was perfect. It works well for layering and can also be dressed up. It is not clingy at all. The quality is great.
