Got these for my husi. He was very pleased with the look and feel of it. Danced all night at his sister’s wedding. These bad boys were perfect with his sage coloured suit! He is an 8 1/2 and we got his exact size Fit perfectly with no complaints. Material is really strong too and the price was the best overall.

Decent value on comfortable motorcycle boot

Size: 11, Color: Black

I would give 5 stars, except I don't ever give 5. But these are 4.87. My feet don't like hard soles, but these boots are pretty comfy. I buy "dress" boots to ride a motorcycle, long story. My favorite was discontinued, and I dislike designer anything. But, these weren't toooo expensive, and turns out, they're comfortable enough, good-looking, and excellent for motorcycling.
