Additional Notes

Understanding the Code Size of The traditional Merino Wool Sock

A typical code number of the Traditional Merino Wool sock starts with 1 letter and followed by 3 digits. The first 2 characters of a code size, such as A1, A2, C2 etc., refer to the width of the sock, Top x Toe. The last 2 digits (in red above) indicate the length.

For instance: In the table above you can see that the width of the A1 sock is 7½ x 4½ (top x toe). Therefore all A1 socks have that width. So, if this is the correct width for you and you need a length of 20" your code size is A120.

Some code sizes also have one or more letters following the 3 digits. These extension letters indicate the thickness (number of plies) of the sock.

Because the strands of wool we use in our socks are finer than other brands the ply rating of our socks may be different to the one you are using now. View this Comparison Table with the Knit-rite brand.

Extension Letters

XL (Extra Light) = 4 ply. Thinner than Standard.

XH (Extra Heavy) = 8 ply. Thicker than Standard.

BL (Blue) = 8 ply. Thicker than Standard.

No extension letter = Standard 6 ply.

From the table above we can assume, for instance, that A318 has a Standard thickness of 6 ply with measurements of: 18 x 9.5 x 6.5 (Length x Top X Toe). And A318XH has the same measurements as the A318 only thicker (8 ply).

Measure your stump to determine the flat measurements of your sock

1. Measure the length of the portion of your stump that fits into the socket of the prosthesis. In taking down this measurement also allow for another 2 - 3 inches for folding down over the prosthesis.

2. Measure the circumference around the top end. The Top end measurement refers to a line near the top edge of the prosthesis.

3. Measure the circumference around the toe end. The Toe end measurement refers to a line approximately 2 inches from the lower end of stump.

Now divide the top and toe widths in 2. With these measurements, of Length x Top x Toe, go to one of the tables above to select your sock.

Alternatively, send your stump measurements to sales@hellersocks.com and we promise a prompt reply. Before emailing see Contact Us for some important notes.

In your email to us you may include some helpful information such as:

a. Your preferred material. ie. 100% wool, Woolblend, CoolMax etc.

b. Details of the sock you are currently using, i.e. material, weight (ply) etc.

c. Let us know if perspiration is a problem.

d. Any comment you might like to add, please do.
