Bonne qualité

These are great looking boots and they would have been super warm. Unfortunately though, I bought my normal size and they were too big (despite the reviews saying they fit TTS). I had to return them. I wished I could have re-ordered them in a 6.5 but they are all gone!

Great boots...but too big :(

On m’avait dit que les bitte Merrell était étroit mais je n’avais jamais expérimenté. C’est vrai celles-ci sont assez étroite. Jet eu un peu mal aux pieds après la première fois mais je crois que le matériel à l’intérieur va se contacter et laissera plus de place à mon pied. Sinon aucun commentaire négatif.

Chaude mais étroite

These boots were very well constructed and fit true to size. They were very comfortable. I ended up returning them because I am hoping to find something without laces but if you don’t mind lacing them I think these would be great. They seemed to have really nice grip. They looked good too. Not too bulky!

Nice duck boot

I am a customer generally wearing a Size 10 boot for wide foot. This is a very pretty boot but the gap for entry of the foot is very tight as the gusset is not elastic, but rather a tight rubber with no give. Once you squeeze your foot in, then the toe area is ample.
I will cut the gusset to improve foot entry.
