A pair of high-heeled shoes are playing a key role in ladies' daily life. High-heeled shoes are full of attraction to most girls for they can make girls feel confident and show their temperament. Under these circumstances, how to choose one pair of shoes is a hot issue. As far as I am concerned, the most important factor is that I am comfortable and not easy to fall down.   On one thing, the heel can not be too high. If it is too high, it is easy for us to fall down because it is not convenient to walk and make us be out of balance. At the same time, the heel can not be too thin because it is hard for us to stand up when we wear a pair of thin-heeled shoes. Therefore, the heel with a middle height and appropriate thickness would be ok.     On another, it is wise to choose the shoes with flat bottom. In this case, it is nice for us to walk and we will feel free even if we have to walk fast.   Thirdly, the materials are critical and soft materials are good to our feet. As a matter of fact, when we wear a pair of new shoes, it is easy to make our feet hurt. So if the materials are soft, it can avoid the bad things happening.   At the end, it is wonderful to choose the shoes with certain heel in front of the shoe. If there is a certain heel in front, the heel in the back will be a little low accordingly. In this way, it can be helpful for us to keep balance and stand well.   In a word, when we choose high-heeled shoes, we should consider its materials, heels and so forth.
