Too narrow at the toes, even for narrow feet

Too narrow at the toe. I have narrow feet, but I could feel my toes being squished as soon as I stood up in these.. Bummer.

A chique set of sunglasses for any trendy woman
Color: Black/Dark Grey, Lens Width: 53 Millimeters, Color: Black/Dark Grey, Lens Width: 53 Millimeters
I love these pair of sunglasses! I’ve never been really able to wear them before lasek. But it’s important to now and the glasses are a true 100% UV blocking. Packaging is really nice done and the green case complements the emerald piece in the glasses themselves. It came with a cleaning cloth which is nice to keep in your purse.
The sunglasses have a dark tint. These pair frame my face nicely and I have a rounder face. It’s not uncomfortable on the nose bridge and the frame is quite durable. It’s lightweight and there’s no pressure on the ears. They are well made and are perfect to dress up an outfit. I prefer simple frames with a special touch and the green emerald piece take these up a notch . So excited for summer!

Wow! Quality glasses with a beautiful design.
Color: Black/Dark Grey, Lens Width: 53 Millimeters
It seems like you're frequently given the option between fashion or quality in the sunglass marketplace. A lot of the fashion eyewear simply falls short on lens quality, durability, or comfort. These glasses have it all. The lens are fantastic and clear, the quality of the frame is very high end, and the comfort of wearing is incredible.
Then there is the fashion aspect. These are true swarovski crystals and are every bit as gorgeous as you would expect from the name.
I'm thrilled with these sunglasses!
