Snow-shoes have undergone a resurgence in popularity over the past few years, and provide the best means of "bushwalking" in the snow. Compared with skis they are easy to use, and much much easier when carrying a heavy pack. They may not offer the adrenaline rush or speed of skiing open slopes, but are more manoeverable off-track, particularly amongst trees and can be worn with normal walking boots.

The principle of a snow-shoe is simple - by distributing weight over a larger area than offered by the sole of your boots, the pressure applied to the snow is less than that required to sink up to your ankles (or knees!), as can happen after a fresh fall or even a slushy base during the spring thaw. In icy conditions slipping can be more of a problem than sinking, so most current designs also include a means of gripping the snow.

These types of snowshoes were difficult for walking up or down steep slopes and the wide stance needed to accommodate them could become very tiring after just a few kilometres. Over the past 20-30 years snow-shoe design has been revolutionised by the use of lightweight materials (aluminium, plastic), the incorporation of crampons or other mechanisms for grip and easier to use bindings. Width has decreased, allowing a more natural walking posture.

There isn't any advanced technique needed for snow-shoeing, a few basic tips will aid in quickly getting used to them:

• First and foremost, just walk normally, keeping the shoes parallel.
• Use trekking or X-C poles in conjunction with them.
• Stepping backwards is difficult (tails tend to dig into the snow), step around in a circle or use a kick turn.
• Kick in when going uphill.
• Keep your weight over your heels when descending.

Most models of snowshoe come in just three sizes; the size you need is dependent solely on weight, not your height or foot length. Weight also includes your pack, so planned usage (day walks or overnight camping) may affect what size you need. Here's a summary of three of the most commonly available snow shoes from Australian retail outlets. Listed weights are for the 'standard' size, rated for a load of up to 100kg.

Yowie Cost: $250-$300 Weight: 1.18kg/pair. A moulded plastic base, no moving parts and a simple design makes Yowies ideal for flat snow country and walking around in the snow without a heavy pack. The patterned base achieves grip on snow in a similar manner to patterned X-C ski bases, while aluminium cleats provide grip in icy conditions. Disadvantages: Not good walking up and down or traversing steep slopes. The binding is difficult to use when it gets wet and freezes.

MSR Denali Classic Cost: $300-$400 Weight: 1.74kg/pair Plastic base, with steel traction blades along the edges and crampons under the foot. For deep snow conditions, or when carrying a heavy pack, the surface area of this model snowshoe can be extended using flotation tails (~$70/set, available in 10, 15 & 20cm lengths). Good traction, easy-to-use (freeze-proof) binding. Disadvantages: Only a two-strap binding. The steel traction bars are sharp and can damage the plastic top of the shoe.

MSR Lightning Ascent Cost: $500-$600 Weight: 1.59kg/pair Aluminium frame, with a "televator" (heel-lift bracket) making ascents easier and more comfortable. The best-performance snow-shoe, excellent traction in steep and rugged terrain. They also come in a women’s version which is narrower than the men’s. Its main disadvantage is the relatively high price.

The increased popularity of snowshoes means that they can be hired at many ski shops (typically $20/day, $30/weekend) although it is advisable to check first. Some offer Yowies, others "classic" (usually MSR Denalis), whilst a few offer a choice. This provides a handy try-before-you buy opportunity.

Baw Baw plateau (Aug 7th) is ideal for beginners, as it should be on snow all of the way without any major climbs. Mt Buller via Klingsporn track (July 31st) is on a fairly sheltered route and steady gradient. Note that the climb (and descent) is over 1000m (hence the M-H rating); if you aren't fit enough to walk this type of route, snow-shoes won't make it easier, but they won't seem more difficult either.
