Boots outperformed many other expensive “name” brands especially in keeping feed dry on a recent walk in Tasmania

Good boots so far

I was looking around at other similar leather walking boots, but for the money, so far these have been really good. I've used them for the morning dog walk of approx 2hrs every day for the last few months, which have been particularly 'weathery', and never had wet feet. They're comfortable and sizing is good. The grip in the woodland much and loam is superb. On the wet days, they certainly kept me upright on some slippery and muddy paths. Was interesting that there was no box or care instructions in the package that you would get with other brands, but I guess that's just less waste to deal with. I think there is a large label on the inner of the tongue that may have some info although not managed to read it so far. Looking forward to some longer hikes with them on the local coast paths and Dartmoor.

I would recommend

Given the mixed reviews I wasn't sure about the boots. I've worn them every day for 4 weeks on a range of walks from 1 mile round the park to a 6 mile walk in the country. My views are: Comfort: out of the box comfortable & no issues Waterproof: stayed dry in wet grass, mud & puddles Grip: as good as previous boots of various brands Overall: does what I needed at a relatively low price.

1 Year Review - Still Good!!

A very good boot. I've worn this boot for a year now. Through all terrain, it seems to hold up. It has been very good in the wet and even held up against deep puddles - not had a wet foot yet. The boot was a bit stiff but mine seemed to bed in nicely - although after a 7 hour trek, I am ready to take them off! I'm sure that would be the case for any boot mind! I've not really kept them clean or treated them with anything and they are still doing well.

Tight fitting and toe too hard

Have used these for a number of hiking weekends in a row now and have got blisters each time. The toe cap on the end digs in and even with loose lacing the top of the boot is also uncomfortable. Thought that with time the boots would wear in but this has not been the case. Disappointed as have bought some excellent things from decathlon in the past.

Love them

I am a dog walker so wear these boots all day everyday, amazingly comfortable & waterproof. Because of the distances i do, with each pair i buy a decent pair of inner's but that just something i have always done. I'm on my 3rd set now & they are just starting to wear out & let in a bit of water BUT Strava tells me i have done over 700 km's in them so really not complaining. Great value for money, when these ones let go i will certainly just by another pair.

Not waterproof

Great from comfort point of view but definitely not waterproof. They take water through the leather into the boot and leave you with wet feet. Not great when that's a selling point

Good support & cushion

I used this shoe recently on Pangarchulla & Kauri Pass Trek, was very happy to see better cushion of the shoe & the support to the foot. Although it needs to be break in before one go for a trek, atleast of 5-7 days. Rest i liked the product knowing it has good grip & waterproofness.

Must Buy

Excellent performance

Badly Engineered Product

Used this product for jus 5 days..stitches started to tear out..outer leather Lining along the stiches started to burst.while wearing it puffs up by the sides looks odd. Even the material claimed to be leather does not seem so.

Excellent Boots | Waterproof| Protection | Comfort

The has been the ultimate Himalayan trekking boots. Super Comfortable, Very nice cushioning and grip. I used it in Winter Kedarkantha trek and In Hampta pass trek during the summer. The boots were perfect for both seasons. HIGHLY RECOMENDED.... I suggest to use waterproofing leather grease after each usease before storing to make the boot last very long.

Not comfotable

Very bad product

Additional Product Information

Lining and sock of

  • 100% Polyester cationic

Sole with grip

The grip of our soles is certified. To be awarded certification, the boots must pass laboratory tests to assess the grip rate on different surfaces (Smooth, Rugged, Dry, Wet). To validate these tests, we assess the quality of our soles in the field, in the mountains, by a panel of representative testers over 310 miles

How waterproof are these boots?

This boot has been validated by a waterproofing test at 30,000 repeatable flexes, i.e. 9 miles - 6 hours of walking, in water up to the mid-upper, which today guarantees a very good level of waterproofing for your boots. --> Our assessment indicates a LEVEL OF 3/5 giving 6 hours of waterproofing when hiking in the rain. The details of tests carried out to assess the waterproofing of our boots is below, in the features section.

Making waterproofing last longer

A boot's waterproofing is often undermined by water getting in from the top of the boot. To keep your feet dry for longer, it is therefore advisable to use a waterproof gaiter or mini-gaiter that will prevent not only water from getting inside through the top, but also pebbles, sand, etc. It is advisable to use a waterproof spray several times a year. This restores the original water-repellent properties and prevents staining.

Care advice

1 / Use a brush and/or sponge to clean the boot and remove any dirt or mud. 2/ Then leave to air-dry, away from any heat source. 3/ Finish by using a re-waterproofing spray to keep optimal water-repellency of the upper and extend the life of the boot.

Which size should i select?

Which size should I select? For hiking, do not hesitate to buy 1 size larger than the usual size to guarantee excellent comfort on the descent and to avoid toes rubbing at the tip of the boot. Tip: Keep your toenails short and, before making your descent, check that your lacing prevents your foot from sliding toward the front of the boot.

5 levels of waterproofing

During the waterproofing test, we test 5 levels of waterproofing: 2,000 flexes (approximately 2.5 miles, 30 minutes of walking) 10,000 flexes (approximately 6 miles, 3 hours of walking) 30,000 flexes (approximately 9 miles, 6 hours of walking) 50,000 flexes (approximately 12.5 miles, 8 hours of walking) 100,000 flexes (approximately >12.5 miles, 24 hours of walking)

Waterproofing test

Our boots are laboratory-tested according to 2 successive tests Test 1 / We test the efficiency of the membrane only when it is put under pressure and placed in water, checking the absence of water at the surface, like when you test a "punctured inner tube. Test 2 / The assembled boots are placed on mechanical arms that simulate walking and are half immersed in water. They complete thousands of flexes to check that the inside of the boot remains dry and it is therefore waterproof.

Buying tips / how do you try your boots on?

How to choose your boots: 1. Try on both boots, standing up and wearing the socks you use for hiking. 2. Tighten the laces correctly 3. Check the following 2 areas of comfort: the base of the heel and the front part of the foot going down. 4. Get up to walk with the boots on. 5. Try on several sizes and models. 6. Wear your boots for increasingly long periods to wear them in
