What does the size mean 9B (M) ?
26781
9 is the length and B is the width. The (M) stands for "medium." B always represents medium, the (M) is redundant. I guess they say (M) in case someone doesn't know what width the B represents. AA is narrow, D is wide. Numbers always indicate the length, letters designate width.

I'm assuming by size 9 you are referring to your shoe size. If so, you will need a large. I wear a size 9 shoe and the large Futuro is perfect for me.

#3 men's 8-9 means 8-9.5 in Spenco sizes, but as far as I know EU 43 is US 10, so then you need #4. Bigger insoles can always be trimmed to fit, while smaller ones cannot be made bigger.

9 mm is shorter than 3/8 in and 10 mm is longer than 3/8 in. so either one of those settings

You go by their weight... 9-13 lbs needs medium. Less than 9 lbs needs small. Greater than 13 lbs needs large.

I ordered a MD and I wear a size 9.5 womens. Works well for me. It's supposed to be rather snug.

First of all, they sent me a Medium. I believe that is the sizing of the chest strap since the watch can be adjusted for personal snugness. I measured the watch strap it is close to 9". Hope that helps!

B is the size and highly adjustable is the type. A B C sizes (small to large). Basic (cheaper) vs highly adjustable.

We have a British Berkefeld standard which uses 7", and bought the 9" by mistake. The 9"fit just fine.

Read the product description below the item and I believe the "select size" drop-down refers to those numbers there i.e. 25 12M etc. I do not know what the M or D stands for but the product description lists a number and the model it fits.
