The Spantik is a much more comfortable alternative to technical plastic mountaineering boots and is just as capable. La Sportiva have created a very warm yet technically capable boot by using a double soft boot construction that has the comfort of summer boots with the full technical climbing attributes of stiff and heavier plastic boots. This ingenious construction reduces weight and really speeds up drying time which is crucial if you are on a multi day route. The outer boot, whilst being hugely supportive and protective also allows flexibility for long walk-ins and has a unique overlap opening that makes getting the inner boot in place much easier. The outer is made from a fusion of synthetic materials that do not absorb water, dry quickly and features a moulded TPU ankle spoiler that enhances the support and stability required for technical routes or even skiing. The boffins at La Sportiva have designed a quick and easy way to lace the boots, a single lace is locked into place using an ingenious mechanism that eliminates knots and can be easily secured whilst wearing heavy gloves or mitts. The inner boot itself is a work of art, they are very different to the usual shapeless foam efforts often found in hard shell boots with well placed padding and supportive fabric overlays around the instep and ankle. Like the outer boots they use a speed lacing system secured by a Velcro tab. This system is quick and easy to use and holds the lace tension securely. The inner can also be heated to achieve a true custom fit, just follow the instructions carefully! Whilst the inner and outer boots provide excellent insulation the majority of the cold is felt through the sole, as that’s the bit that’s in contact with the ground. Traditionally boots overcame this problem by making the soles dense reducing climbing sensitivity and increasing weight. The Spantik however uses a unique 5mm thermal structure carbon fibre midsole to provide strength and support without sacrificing feel and sensitivity. Shock absorbency and further insulation is provided by a micropore EVA midsole with TPU inserts to provide the support for crampon bindings. The outer sole is the aggressive Vibram Montagna which has a rolling rocker for easier walking, deep lugs for loose ground and a dedicated climbing zone for…climbing! Overall the Spantik is the perfect expedition, winter Alpine and technical climbing boot that will protect you from extreme cold in the most inhospitable places on Earth.
