Cementing is performed traditionally according to your protocol:

• Cleaning
• Carding (It is necessary to break the surface of the sole for better halogenation.)
• Halogenation
• Cementing

For marking and displaying, set the press to roughly 2 to 3 kg. In general, due to the softness of the material, it is recommended to apply minimum pressure on the sole.

For stitching, adjust the tension of the thread to the minimum tension.

See glue manufacturers' cementing recommendations:

We suggest milling the sole once fastened. Although it is a more delicate operation, it is also possible to mill it directly and to affix a welt.

Recommended tools:

• Trimmer with small blades or 80 to 100-grain paper.

To reduce small particles which remain on the LACTAE HEVEA® sole during milling, it may be useful to dust the sole with talc.

The LACTAE HEVEA® sole is a living product and during milling, depending on the color, a milky color may appear, like the milk from which it originates. On contact with air, the surface dries naturally and its natural color is restored, through to the centre. These ready-to-use soles retain all of their comfort and intrinsic qualities.

Here is an example of how the color changes during milling:

The LH sole is a living product and therefore, when exposed to light or heat, may develop a light white veil, commonly known as "White Blooming". It will disappear by cleaning with water, but it may come back again. To avoid white blooming, it is recommended to store our Lactae Hevea soles in a tightly sealed box, away from drafts. To remove it definitively, we recommend applying a siliconized water solution (1 to 2% of neutral silicon oil) using a brush once the shoe is finished.

It is possible to engrave your own logo on our LACTAE HEVEA material. This video will give you a clear overview. This operation can’t be carried out by Reltex, please contact a specialized company.

For the same color, each production has its own shade.

This is due to the natural color of hevea milk, which has a different influence on the desired color each time.

On the same sole, the color also caries depending on the thickness; the heel thus becomes slightly darker than the half sole. Furthermore, over time, the colors develop more marked shades.

The soles are delivered paired up in the same shade. Regarding our "Natural" colored soles, these may also be subject to shade variations. Also, all our "Natural" colored soles are paired up with feet of a similar shade, and attached with an elastic band. Please do not unpair the shipped soles.

Below is an example of how colours can vary for the same production:
