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.

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.

I love these. They fit perfect in the waist but are roomy else where.
