A modern evolution of the classic ballet flat is designed for everywhere the day takes you. Discover The Fonteyn, handcrafted with our signature comfort-first details plus a chic, subtly squared-off toe and slightly higher rise.
We recommend ordering ½ size down from your typical US shoe size. Because sizing down also reduces the width slightly, we'd recommend sizing up in width to help maintain a comfortable fit through the front of the shoe.
The Fonteyn is designed for a glove-like fit and should feel comfortably snug right out of the box. The soft suede will gradually soften and mold to your foot with wear.
Fit tip: The adjustable bow isn't just a design detail—it helps tailor the fit to your foot. If you're noticing a little heel slippage or would simply like a more secure fit, gently tighten the bow. Watch this video to learn how to adjust the bow properly..

"I love this shoe! The color is beautiful, and the fit is so comfortable! I initially ordered a size too large; customer service was prompt and very helpful in assisting me with my exchange. I am relatively new to Margaux shoes, and I have purchased five pairs already!"
"I had forgotten a pair of flats on a recent work trip, and was so grateful when I found the Fonteyn in the SF store. These were a perfect fit, perfect shape, and were exactly what I needed. Got many compliments. These sales associate was incredible helpful. Loved the space, too."
"I love wearing ballet flats, usually the traditional almond toe versions, and bought the Fonteyn version as an alternate. The slightly higher cut and barely squared toe is a beautiful option between a ballet flats and a loafer. They are comfortable to walk in every day and yet elegant and versatile."
"I love these. They needed almost no breaking in. Randomly, they do seem a little big to me? Which I was surprised by — I'm a pretty true 6, if anything more 6. 5. Also, as far as flats go they ARE very comfortable, HOWEVER, all those Vogue and Strategist and whatever reviews saying you can walk 10k steps in them must have been written by someone with VERY young knees and ankles."
"The color of these shoes was close to midnight, almost black. I was looking for a more true navy"
"I love the square toe, and they are just as comfortable as the demis. With size 4 feet, I really appreciate Margaux’s extended sizing."
"These are going to be an excellent staple for fall and winter. Lovely fit and shape with nice structure. Blue/black is subtle, very nice."
"These are amazing and I have never found shoes that fit me as well as these flats. I love the different size and width size you can choose from and they are wonderful"
"Have not worn these yet. It’s still summer in Texas, but they are beautiful and can’t wait to wear them. I wear an 8.5 and these fit true to size"
