Some fears and taboos exist on their own and do not have clear explanations. From grandmother to mother, from mother to daughter, the belief is passed that you can’t sleep with a wet head, sit on a stone, cut vegetables or walk in rubber slippers … Is it really impossible? Let’s figure it out.
The logic, at first glance, is simple: if the sole is flat, then you will have flat feet. But in this regard, flip-flops-flip-flops are no worse than sneakers. In fact, flat feet do not develop because the sole is flat, but because it is a “slap” – it does not have a back and is not fixed on the heel.
Pronation is the deflection of the foot, a natural shock absorber that allows you to properly redistribute the load on the ankle and adapt to any terrain on the earth’s surface. So, when your heel is loose, you’re tensing your forefoot not only to walk, but also to hold on and not lose your slipper. At the same time, the foot bends in much the same way as when walking in very high stiletto heels. Ligaments practically do not cushion – and flat feet develop.
Simple human logic dictates that spurs can form due to the fact that a loose heel counter slaps the heel all the time. The blows themselves, of course, are not too traumatic, but the soft and poorly fixed sole really creates problems.
Because of this feature of the slippers, it is possible to overload the plantar aponeurosis – the ligament that provides support for the arches of the foot. When it is overloaded, inflammatory processes can begin, which will cause pain when walking and vertical load on the feet.
You feel it as a shooting pain in the heel or pain when stepping on (heel spur). In medicine, this is called fasciitis, or inflammation of the plantar aponeurosis.
cystitis and infertility
Quite a well-hyped topic: hypothermia of the legs leads to adhesions in the small pelvis, which means infertility. Well, or at least to cystitis and thrush. That is, whatever one may say, this horror story is more likely against hypothermia than against rubber slippers.
That is, hypothermia can really lead to an exacerbation of cystitis, urethritis, vaginitis. But are you likely to wear rubber slippers in cold weather? In any case, there will be no more harm from walking in slates from the hotel to the sea than from swimming in the sea itself. And definitely less than from walking through the puddles in Moscow this summer. Adhesions and infertility have nothing to do with the shoe model at all.
Pain in the knees
And finally, joint pain, which traditional medicine associates with rheumatism, and this in turn with the harmful effects of rubber materials. In fact, rubber is not to blame: you must consider the same risks when wearing plastic, rag, cork and any other slates. The lack of fixation of the foot forces you to distribute the load in an unusual (unnatural) way in order not only to maintain balance, but also not to lose your shoes. This increases the load on the knee joint – and it wears out ahead of time.
Of course, if you wear flip-flops for only two weeks a year to run from your hotel room to the beach and back, then all the existing risk factors will not have time to add up to a real threat. But if you wear slippers all summer … In general, it’s better not to!
