Ankles are very inflexible when it comes to body parts. The skins around the ankles which are mainly across the joints on our feet are taut and rigid with the rough use over the years. The pressure of constant walking and standing make them just like that. Even uncomfortable shoes apply a lot of pressure on them. In dry seasons when the skin contracts and get flaccid with the lack of moisture these regions tend to crack.
Cracked ankles can turn to be very irritating and if not dealt with even painful. The best way to deal with it is to constantly moisturize your ankles with a good moisturizer with basic vitamins like vitamin A and E. even soaking your feet in lukewarm soapy water is a good way of cleaning them and keeping them from getting cracked any further. There are many creams and lotions in the market which can e compared against their reviews and bought for just this purpose.
