These arrived today and fit to size! They look amazing and so far seem comfortable. The quality seems good but time will tell as these are my going out type of footwear.

Top quality for the price but a little tight in the toe box
Size: 8.5, Color: Black Full Grain
A little tight around the toe box for me and I don’t have a particularly wide foot. But the quality is great and the look is awesome. Hoping they stretch out a bit with some wear!

Everyday Jeans With A Great Blend
Size: 32W x 33L, Color: Medium Wash
These are my new daily drivers. I got the Medium Wash in 32W x 33L, and the size and fit are true to size—a modern slim fit that's not too tight. The key is the stretchiness; there's just enough elastane in the material to make sitting, driving, and bending incredibly comfortable, unlike traditional stiff denim. The softness is immediately noticeable compared to raw denim. For long-term durability, the stretch blend should hold up well with normal wear. The functionality is perfect for casual work environments or weekend outings. Excellent value for a comfortable, stylish jean.
