La Sportiva TX5 Evo Mid GTX Hiking Shoes

Size Guide
Size Guide - LOWA

Even if lengths of a LOWA shoe size are roughly identical, shoes sizes are not stand­ardized. This can result in minor differences in size from category to category and from footwear manu­facturer to footwear manu­facturer. Furthermore, the shape of the shoe plays an important role in the perception of size. A narrow shape makes the shoe appear smaller, while a wide shape tends to make the shoe appear larger. Of course, your feet also change during the course of your life. As you get older, they get wider and longer. That’s why LOWA recommends you should always try on shoes and check your size in the shop before you buy them. When trying on shoes at a retailer, you should also remove the inner soles and stand on them. This tells you very quickly whether your feet have enough room.

Your best bet is to try shoes on during the afternoon, as your feet swell a little during the course of the day.

This size chart is meant to be a guide for sizing LOWA footwear. Shoes need to be tried on and fit with appropriate socks in order to determine correct size. Please note that we cannot guarantee sizing as all feet are unique. 

The general rule is to order the same size LOWA Boots as your standard street shoe size.
