Each numbered orthotic is suitable for a different foot shape/problem. One needs to go to a store (many large drugstores or Walmart) that has a Dr. Scholl's orthotic fit machine to determine the right number for your feet.

No difference. One just omits the mm and the other includes it. Same exact time size.

i don't think there is any difference between the numbers. the "U" on the end is primarily a region indicator (JP for japan, USM, U, US, and so forth). the primary difference may be the information sticker or imprint on the battery itself. the charger does work for both of these rather well.

I am not sure, but it also shows the number you are asking about without the S on the end of the number.

Sorry I couldn't give you exact numbers. The product is a quality item that "works". NO regrets!

Sorry, mine both have completely different numbers. It is a bit strange that only the covers have labels as to what step it is.

I cannot figure out the price difference since it appears there is no other difference. Sorry.

No. They are each numbered differently. There are two dots above each number and a line beneath each number.

The numbers are inside the negative space, the area around the number is what gets stamped with unique sized rectangles. They all vary, but roughly 2" is average height.

They have numbers. Dot dominoes are also available. In my opinion, the numbered dominoes are easier to read.
