Winter holidays are fun. Going into the mountains for skiing and fun in the snow is always a thing to look forward to. It is more enjoyable if you manage to arrive in one piece instead of ending up in a ditch. It might also be worth a lot of money as many countries hand out hefty fines if you haven't readied your car for snow and icy conditions on roads and mountain passes.
Hiking is the perfect fat burner. But you have to do it in the right footwear, or you might expose yourself to unnecessary dangers. Before setting out to countryside, the hills, or even mountains, go get some decent shoes or boots. Converse, sneakers, or slippers are not made to trek for hours through rough, wet, or slippery terrain. Slithering down a rain soaked muggy hill in shoddy shoes is not my idea of fun.
