Model: Question
Dear Amy,
Shoes with high heels are in fashion
And they make me feel tall
But I can’t walk in them.
What should I do?
Dear maria,
Dear Maria,
You should always wear shoes that are comfortable.
(first reason) High heels in particular are very unhealthy and can cause problems with your feet, legs, and back.
(second reason) Also, they are unsafe. Women in high heels fall more that women in flat shoes.
Take my advice – This is one fashion you should avoid.
