Technical Information

MADE IN EUROPE MANUFACTURING : 100% of Forclaz boots are manufactured in Europe
These boots are manufactured in the European Union, in Romania, in a factory that specialises in making hiking boots (SKANDIA). Main upper component: Made in France For greater transparency, here is the link to our French partner: https://chamatex.net/marques/matryx/ Tip: copy/paste the links on this page into your preferred search engine)
VIBRAM®. Grip and traction of our soles
Our VIBRAM® branded soles provide excellent grip on all dry, earth or rocky terrain. Just awesome! The VIBRAM® notching also gives you grip adapted to muddy or wet terrain. Medium width sole: the wider the sole, the softer it is. Therefore, with this sole it’s comfortable to walk on most trails without losing stability.
MATRYX® technology? ULTRA-RESISTANT and very technical textile with a weaving technique rooted in French expertise.
The part of the upper, which is used the most in the field, is made of a MATRYX EVO fabric. It is a jacquard with a built-in lining. Technical compound of a PA warp coated with 550DTEX PU and a PA weft coated with 550DTEX PU. 167Dtex PES lining Aramid yarn throughout the upper to ensure good support
The durability over time of the MATRYX® technology is undeniable. The French design and the recycled polyester yarn used in the composition of certain textiles add to our contribution to developing sustainable products.

This boot has been tested and validated for 50,000 flexes repeatable, equivalent to a 20 km walk, in water reaching the mid-upper. This now guarantees a good level of boot waterproofing. --> Our assessment indicates a LEVEL OF 4/5 giving 8 hours of waterproofing when hiking in the rain. The details of tests carried out to assess the waterproofing of our boots is below.
WATERPROOF BOOT OR GAITER? it’s not necessarily one or the other! it provides additional protection
The waterproofing of boots is often compromised because water gets in at the collar of the boot. --> To keep your feet dry for longer, it is advisable to use a waterproof gaiter or mini-gaiter that will prevent water as well as pebbles and sand from getting inside through the top of the boot. Model perfectly suited to this TREKKING GAITER MT500 BLACK €15 https://www.decathlon.co.uk/p/trek-500-trekking-gaiters-black/_/R-p-124466?mc=8347880&c=BLACK
How to make the waterproofing of this textile model last longer?
Even though this model has a WATERPROOF MEMBRANE (waterproof, breathable), it is recommended you use a re-waterproofing spray a few times a year to restore the original water-repellent properties and prevent staining of the outer material. --> It revitalises the water-repellent properties of the outer material (water runs off and doesn't soak in). Each fabric section is sprayed taking care not to forget the thread in the seams (water loves seams!!)
Care advice, application of the waterproofing spray
1/ Use a brush and/or sponge to clean and remove any dirt or mud. 2/ Then leave to air dry, away from any heat source. 3/ Shake the WATERPROOF SPRAY can €5 4/ Spray the product from a distance of 25 cm 5/ Leave for at least 10 minutes. Caution: Do not rub or wipe. Link to SPRAY below: https://www.decathlon.co.uk/p/100-ml-waterproof-stain-resistant-spray-for-leather-and-textile-walking-shoes/_/R-p-312940
No eco-design without great durability in our products!
As well as the various laboratory tests, these boots were tested in the field by passionate trekkers during a 500 km DURABILITY MISSION TEST, on the GR5 and trekking trails of the Canaries. Check out the film of this mission test by clicking this link: https://www.youtube.com/watch?v=L5o2h5v5RsU
Environmental approach: Eco-design / Sole / X ankle system
Our mounting sole is made from 80% recycled plastic. Our ankle skeleton support (the black “X” part) is made from 100% recycled plastic. Our main upper component is made in France. Production and assembly is European.
Environmental approach, Dope Dyed
DOPE DYED black yarn in the upper. Textile dyeing requires a lot of water but also produces waste water from the dye baths. To reduce the environmental impact, we have opted for mass pigmentation (also called Dope Dye), integrating the colour pigments from initial thread manufacture. This technique saves a large quantity water and considerably reduces CO2 emissions. What's more, the dying of the clothing lasts longer as a result
Lab tests
Laboratory tests were conducted to test the following elements: - tearing of the eyelets and straps - bonding of the sole - toxicology - UV-resistance - abrasion of the sole and components of the upper - accelerated ageing
Can crampons be used with these trekking boots?
This model of trekking boot allows for the occasional use of STRAP-ON CRAMPONS ONLY. It is sufficiently rigid for the occasional use of strap-on crampons while guaranteeing extremely good comfort when walking.
Which size should I select?
Which size should I select?For hiking, do not hesitate to buy one size larger than the usual size to guarantee excellent comfort on the descent and to avoid toes rubbing at the tip of the shoe. Tip: keep your toenails short and, before descending, check that your lacing prevents your foot from sliding forwards inside the boot.
5 levels of waterproofing
During the waterproofness test, we test 5 levels of waterproofness: - 2,000 flexes (approximately 4 km, 30 minutes of walking) - 10,000 flexes (approximately 10 km, 3 hours of walking) - 30,000 flexes (approximately 15 km, 6 hours of walking) - 50,000 flexes (approximately 20 km, 8 hours of walking) - 100,000 flexes (approximately >20 km, 24 hours of walking)
100% waterproofing laboratory tested
Our boots are laboratory tested by 2 consecutive tests. Test 1: We test the effectiveness of the membrane alone immersed in water under air pressure. We simply check for any bubbles on the surface like a pierced air chamber. Test 2: Thanks to a mechanical arm that simulates walking, the entire boots are half immersed in water and they complete thousands of flexes to check that the inside of the boot remains dry and it is therefore waterproof.
BUYING TIPShow to try on your boots?
How to choose your boots: 1. Try on both shoes, standing up, with the socks worn for hiking. 2. Tighten the laces correctly. 3. Check the following two areas of comfort: the base of the heel and the front part of the foot going down. 4. Stand up to walk with the boots on. 5. Try on several sizes and several models. 6. Gradually start using you shoes during your first few hiking trips to break them in.
Co-design closest to the anatomy of the foot in partnership with a chiropodist
These boots were co-designed with passionate trekkers, each bringing their own special skills. For example, one of our co-designers is a chiropodist who helps us to meet the physiological needs of people's feet and to make sure they are comfortable and safe during treks.
