原本只在海滩现身的“人字拖”近几年却成了很多人夏季必备的一款鞋，不过，英国有专家提醒，长期穿“人字拖”可能会导致胫骨骨膜炎及关节疼痛等病症。专家指出，人们穿“人字拖”走路时的受力部位是外脚背，而不是惯常受力的脚跟，这就有可能引发脚踝扭伤或踝关节损伤等病症。此外，因为缺少受力支持点，人们在穿“人字拖”的时候也更有可能会绊倒，从而导致身体其他部位受伤。医务人员表示，“人字拖”对身体的危害跟高跟鞋不相上下，它造成的损伤甚至比高跟鞋的损伤更加严重，因为人们穿“人字拖”的时间更长。据悉，英国国民卫生服务系统每年都要花费4000万英镑治疗此类损伤，每年因这类损伤求医或者入院治疗的人也超过20万。

Flip-flops force people to change the way they walk so that when taking a stride they put pressure on the outside of their foot, rather than their heel, causing long-term damage.

Compared to high heels, they don't look remotely hazardous. But flip-flop wearers would do well to think twice before slipping on a pair.

The National Health Service spends £40 million a year treating injuries caused by wearing the casual footwear.

More than 200,000 people visit their general practitioner or even end up in hospital every year after suffering falls or developing long-term problems.

Once worn only at the beach, flip-flops have become the regular summer footwear of choice for many, with one in five women owning at least one pair.

But experts are warning of the dangers of prolonged use, such as the risk of shin splints and joint pains.

They say flip-flops force people to change the way they walk so that when taking a stride they put pressure on the outside of their foot, rather than their heel, causing long-term damage.

And there is also the risk of serious injury from tripping over.

Frequent complaints include twisted ankles, but some have broken their arms or wrists after falling because their flip-flops caught on uneven ground.

Many also suffer aching toes as they constantly scrunch them up to grip the thong, while there is also the danger of the odd stubbed toe.

Flip-flops are one of the most popular shoes among women, with 15 million wearing them a day in summer, according to shoe firm MBT which obtained the figures.

Mike O'Neill, spokesman for the Society of Chiropodists and Podiatrists, warned of the damage done by wearers forced to adapt how they walk.

He said: 'They land on the outside and then roll the foot inwards putting all the pressure on the big toe. This constant rolling puts pressure on the ankle joint causing it to weaken.

'The lack of support of the flip-flop also causes pain in the tendons on the inside of the foot and lower leg. It can also lead to shin splints.'

And if you're not used to wearing them, they can cause blisters, he added.

Medics say flip-flops are just as bad for the feet as stilettos but cause far more damage as they are worn for longer periods of time.

Emma Supple, consultant podiatrist for the MBT, said: 'Flip-flops are universally popular. They are easy to put on and easy to wear but women do need to be mindful that prolonged wearing on hard flat surfaces can cause considerable foot and leg problems.'

She encouraged women to wear sensible shoes to help recover from summertime injuries.
