Our hiker designers developed these kids #39; boots for half-day hikes, in dry or wet weather on easy trails. Sole coefficient of 0.66 for safety on all terrain Waterproof membrane tested on a 4km walk in water up to the middle of the upper 253 g per boot Exclusive heel cushioning system. Guaranteed comfort and long life. Flex areas and reinforced glue lines. The design of the sole has been the subject of long research at our laboratories, combined with a specific rubber formulation to offer the best grip and traction. Given the variety of different needs, we always seek the best compromise for walking on muddy and dry terrain. During the waterproofing test, we test 3 levels of impermeability, i.e. 2000 flexes (about 2 hours of walking), 4000 flexes (about 4 hours of walking) and 8000 flexes (about 8 hours of walking). waterproof boot exceeds the level of 4000 flexes. A boot #39;s waterproofing is often undermined by water getting in from the top of the boot. Using waterproof gaiters or mini gaiters is therefore recommended to keep your feet dry for longer by protecting the top part of your boots and preventing water from getting in as well as pebbles, sand, etc. Use of a re-waterproofing spray is recommended several times per year. This will help your boots recover their original water-repellent qualities and combat outer stains. Get your kid to try on both boots while standing up, with socks they would normally wear for hiking. Check two comfort points: the base of the heel and the front part of the foot going downhill. Avoid all pressure points when trying them on. Gradually get your kid to wear their boots during your first few hiking trips to break them in. On the internet, you can print out the pedometer and check your kid’s foot length. For hiking, try taking one boot size up from your usual to ensure optimum comfort when going downhill and prevent toes from hitting the toe stop.
