The product consists of a rubber body thermally welded to the boots and straps for suspenders. The body is relatively wide, especially at the chest. Never expect a perfect fit, and if you tighten them enough on the shoulders, you won't be able to easily bend your knees. However, the boots are smaller than the size of the boots you wear (that's why the low rating). If you wear them for a short time, there is no problem, but if you want them for prolonged frequent use, they will hurt you. So if you want them for example for fishing, walking in the river, or working in water, order two sizes larger, something that users have noticed because as I see, the larger sizes are sold out. Keep in mind that the product is Chinese. Also, the soles are hard red (nothing like those in the photo) with no large gaps in the tread, which reduces friction and stability while walking. Hence the slipping on stones with slime in the river. Relatively, it's the cheapest you'll find today in the Greek market, only for light amateur use.
