The best way to break in a glove is to use specially designed glove oil. Glove oil keeps the leather ''alive'' while providing a softening condition and minimizing weight gain. Apply a small amount of glove oil to a sponge or cloth, then use the sponge or cloth to apply the oil to the areas of the glove that are currently firm. Start with the palm, the break point of the glove and then web. Then use the glove oil on all other parts of the glove including the entire inside to help moisturize and protect the glove. Work the glove oil into the leather evenly. Do not apply the glove oil directly to the glove, as it will be too concentrated at the point of application.
Also, make sure that the laces get oiled so they can stay moisturized so they will not dry and begin to crack. Otherwise, the webbing of the glove will come loose. Remember that leather is skin and leather experts tell us not to treat glove leather any differently than you would your skin. Therefore prolonged harsh temperatures (oven, microwave) excessive water soaking, especially use of hot water, abrasives, the salt and acids produced from perspiration and excessive dryness all or individually can be harmful to the glove leather.
