This is a great boot for playing around in the snow.  Lightweight with just enough weight in the sole to ensure your feet come down flush on ice.  Tread has good traction for outdoor use -- not really a hiking sole like some boots ( the ones with knobbys on the sole) but a solid grip nonetheless.  No tying, just a velcro strap to cinch at the ankle and and a pull below the knee to keep out snow.  Put these on, along with a good pair of snow pants and you can stay out in the cold for a long time.

Inside liner is toasty warm and removeable for machine washing/drying if need be - nice touch.  This is my second pair of Kamiks - I have these and a short pair of zip-ups for "city" outside wear.  Well worth the money
