Four Ways to Make Your Shoes Feel Better

According to the American Podiatric Medical Association, the vast majority of people experience foot pain at some point in their lives. The reason for most foot pain is that shoes fit poorly or force the feet into unnatural shapes. 【小题1】 Aside from carefully selecting the right shoes, there are some easy measures you can take to keep your feet from being painful.

1. Stretching Your Shoes

If your feet are rubbing against your shoes this could indicate that you need more width, length or both. However, sometimes going to the next larger size is not a choice, as the next size may be too large. 【小题2】.

2. Using Shoe Inserts (插入物)

Both doctors and those in the shoe repair industry often recommend inserts to increase shoe comfort. 【小题3】.

3. 【小题4】

The way you lace (由带子系紧) your shoes can make a world of difference in their comfort. Lacing them too tightly or incorrectly can make your feet hurt. Cramped toes, rubbing on the top of the foot, and pressure on the big toe can likely be relieved if you lace your shoes different.

4. Wearing Socks

【小题5】.They are usually made of cotton or nylon. Not only do they add an extra layer of cushion to your shoes but they also keep your feet from sweating. This prevents moisture (水汽) from forming in the shoe. Moisture in your shoes can cause blisters and calluses on your feet.

   Could cities that float on the sea solve the problems caused by floods and provide food for the world?

Some scientists think so. The idea is already being tested and they believe that floating cities will provide more homes for a growing population, without having to use land needed to grow food. And they believe floating areas will allow more food to be grown, so that no one in the world is in hunger.

In some places, cities that float on the sea are already being planned. A company in the Netherlands called DeltaSync thinks that sea cities will save the world, with more than one in ten people living in them.

They say sea cities can solve many of the problems the world faces in the 21st century, like not having enough land, more and more people needing homes, fossil fuels (矿物燃科) running low and the increasingly serious problems caused by floods.

DeltaSync says building in the desert is not possible because there is no enough water and that developing ways for people to live in space is still too expensive. So they believe the answer is our oceans, which cover over two-thirds of the Earth’s surface. Their plans for floating areas include using algae (藻类) to produce fuels and food.

More than a quarter of the land in the Netherlands already lies underwater and scientists there have spent years trying to find ways to deal with it. In the city of Rotterdam they already have floating homes.

Bart Roeffen from DeltaSync says, “We have plans for neighborhoods including roads and, in the end, I believe we can build floating cities on the sea.”
