Reviews

Lovely & Comfortable

"There is nothing like a well crafted shoe, attractive in shape, material and comfort. The heel on this shoe is very comfortable and while many shoes highlight the padded foot bed, which this one has, it is of no importance if your toes are getting blisters. This shoe's suede is soft and comforms to the foot, it is not heavy, nor makes any squeeks. I have worn them all day and they are needing no breaking in. Worth the money."

— Kim C. (5/5)

Great sandal

"Love these sandals, just the right size heel for someone that can’t handle a heel. Love the saddle color, matches with everything. I usually am between 8-8. 5 with slightly wide foot and the 8. 5 medium worked well. I think a wide would be too much. They take a little bit to break in but once they do very comfy!"

— Jem M. (4/5)

Beautiful but not for me

"This is a gorgeous shoe and I loved the look and feel, but I have a bunion/arthritis and the straps hit it wrong. I have several pairs of loafers and the city sandal that are amazingly comfy so sad that these didn’t work for me. The return was so easy and customer service is delightful."

— Lucy M. (4/5)

Disappointed

"It is a very pretty shoe but it fit a little wide and did not adhere to my foot so it was flopping off and unstable. Beautiful color and I am sorry it didn't work out."

— Joan O. (5/5)

Too narrow & below expected comfort level

"I have Palermo sandal in regular width size 37 and Marlowe loafer in 37 wide but this sandal in the same 37 wide was way too narrow and the underside of the band was too rough. I’d also say the length was touch long. Loved the color. Wished it worked."

— Ana S. (3/5)

Timeless and Well-Made

"I am a true size 6 in most shoes but needed to size down to a 5. 5. The length is perfect, and I expect the leather upper part of the shoe to stretch for a perfect fit. Great for dressing up or down, and the heel height is perfectly comfortable for daily wear."

— Emily G. (4/5)

Great Sandal!

"Wonderful fit and classy look!"

— Susan S. (5/5)

Blisters

"I love all my Margaux shoes but these caused blisters on my pinky toes. So sad!"

— Caroline D. (3/5)

Very nice sandal

"This is a very well-made, attractive sandal. It fits my narrow foot well. The leather straps aren’t soft, which is why I gave it 4 stars. Overall I am really happy with the purchase!"

— Michelle B. (4/5)

Comfortable, but caused a blister

"Very comfortable overall and I love the style, but the front overlap seam rubbed against my toe and gave me a bad blister after an hour of wear."

— Nadia M. (3/5)
