My wife wears a 7 1/2. Which size would be ideal for her?

Is she is a 7-7.5 M US Then a size 7 should be best, because this shoe stretches about a half size. If she is more of a 7.5-8 M US Then a size 8 would fit best, but might become sloppy over a length of time. Everyone is between 2 sizes like this.

Size says b(m) What does that mean?

b(m) stands for medium width of the shoe. For example if the shoe says 6 b(m) US that means it it size 6 regular(medium) width if it were to say 6 c(d) that would mean the shoe is a size 6 with a larger width . So these boots would be perfect for anyone that doesn’t have extremely wide feet. I️ myself have a little wider that usual and these fit just fine! Hope that’s answers your question

Are these for men? the description says women's classic short ii boot. but on the size choices it's got a m after the size. can you tell me what's go

These are for women and the m is medium. I wear an 8 or 8 1/2. I ordered an 8 and they fit perfect. They are super comfortable and warm. I now have a 2nd pair.
