Cute but no so comfortable
I previously owned a white sperry leather shoe that I bought from Marshall’s for about $35 & absolutely them, they were so comfortable , cute & great price.After running that pair down, I decided to buy another pair and found out the shoe was discontinued. The closest thing to what I had is this, the white crest vibe in leather. I was disappointed that this shoe was not as comfortable and didn’t fit quite the same. The back ankle part of the shoe caved into my skin and hurt. Sadly, I do not recommend this shoe for much walking. I hope Sperry decides to make this shoe more comfortable because it is cute.

Perfect Jeans!
Size: 26, Color: Verified Vintage, Size: 26, Color: Verified Vintage
Love these jeans, so soft and lightweight but with all the usual Levi’s class. I bought them in three different colors. They’re so well fitting and comfortable to wear. Im 5’5 140 pounds and it is true to size. The perfect fit every time.!

Classics! Good material with no stretch.
Size: 28, Color: Verified Vintage
I am in love with these jeans. I ordered another pair in a different wash. I also sized up two sizes but I like the looser, slouchy fit.
