The most common technologies: Waterproof vs. Water-resistant
The shoe industry has created a variety of different technologies for hiking shoes, but the most commonly known ones are waterproof and water-resistant.
Goretex is the first patented membrane technology brand. This consists of a very fine layer of politetrafluoroethylene which, in summary, prevents water from entering the inside of the shoe, while at the same time allowing sweat to escape. It is said that this membrane contains 1400 million pores in just one square centimeter.
This makes it both a water-resistant and breathable technology, which keeps the foot dry and at an optimal temperature. For this reason, it’s recommended when hiking across a river, when it has rained a lot or when rain is in the forecast. The material also dries much quicker than other shoes.
There are different types of Goretex. The Extended type is ideal for warm climates and more strenuous activities; Performance is for any type of weather, but with less physical strain; Insulated is made for winter, with an extra layer; and Surround is the most advanced and breathable type. A few alternatives to Goretex that also use membrane technology include Hyvent, Sympatex and Omnidry.
On the other hand, Waterproof technology utilizes a very different method, which consists of spreading a chemical product over the entire surface of the shoe to leave it completely waterproof. However, as it’s not a breathable material, it’s very important to consider beforehand which activities the shoes will be used for, how many kilometers they’ll need to cover and the type of terrain.
If you plan on going on a long trek, most likely sweat and heat from waterproof shoes will irritate your feet. But if you’re going a shorter distance and plan on being in a humid area for an extended amount of time, such as for taking pictures, this type of footwear works well and will provide protection.
