Footwear is most important. A hike should not be started with shoes or boots that have not been thoroughly broken in. Because feet swell greatly on a long trip, hiking shoes should be at least a half size larger than street shoes. They need not be heavy, awkward shoes--in fact, light shoes are much easier on the feet. Most people are made uncomfortable by high-top boots or shoes which retard the circulation of the calves. Six-or eight-inch tops are sufficient. Soles should be flexible, preferably of some composition which is not slippery when wet. Crepe soles are excellent for mountain climbing and for fishing. Hobnailed shoes are necessary only for grassy slopes or cross-country work. Hungarian nails are much to be preferred to hobs, and only a light studding of soles and heels is most effective. White silk socks should be worn next to the feet, a pair of heavy wool (German) socks over them. Soaking the feet daily in salt or alum solution toughens them. On a hike the feet should be bathed in cold water whenever possible. Hiking trips with ranger naturalists are described under that service. There are many interesting short side trips from all hotels, chalets, and camps. Short self-guiding trails upon which interesting objects of natural history are fittingly labeled have been established at the following places: 1. Around Swiftcurrent Lake (2-1/2 miles). 2. From Lake McDonald Hotel to Fish Lake (2 miles). 3. From Lake McDonald Hotel to Johns Lake (2 miles). 4. From Avalanche Campground to Avalanche Lake (2 miles). Lunches may be ordered from hotels and chalets the night before a trip. If an early departure is planned, it should be so stated upon ordering the lunch.
