Lowa fits true to European standards. The length of the foot in mm is the priority measurement. Your usual size in EU is the right starting point. Note a specific feature: for 273 mm, Lowa officially indicates size 43.5 EU and not 43. Always use the mm/EU chart to confirm your choice.

Lowa does not systematically run small or large. The brand conforms to EU standards. The fit may vary depending on the width of the model (normal vs W version) and the rigidity of the construction. Mountaineering models are more fitted than hiking models, which is intentional for performance.

Yes, your usual size is the right starting point. Check by measuring your foot in mm and comparing it with the official chart. For long treks or with thick socks, an additional half size may be considered. If your issue is width and not length, choose the W version of your usual size.

Take your usual size in EU, confirm by measuring your foot in mm. For day hiking, your usual size generally suffices. For a multi-day trek with a heavy backpack or thick socks, an additional half size is often appreciated. If you have wide feet, opt for the Renegade Wide version.

The Tibet is a trekking shoe with a generous fit. Take your usual size. For long expeditions with a very heavy backpack and thick trekking socks, +1/2 size is often recommended by practitioners. Check that your toes have enough space for long descents.

The "W" means Wide. W models offer more volume at the forefoot and at the ball of the foot, with a heel that remains standard width. If you have wide feet, choose the W version of your usual size rather than going up a size: you will preserve heel support and the correct length.

This is a feature of the official Lowa chart: for a foot length of 273 mm, the brand indicates 43.5 EU and not 43. This may be surprising, as other brands indicate 43 for this length. That is why Lowa recommends prioritizing foot length in mm rather than your usual EU size. Always use the official Lowa chart.

The construction of the sole influences the US women's correspondence. For shoes with cemented construction, US women's sizes are slightly different from shoes with injected construction. This information is specified on the product sheet of each Lowa model. When using US sizes, check the construction method. In EU, there is no difference.

Not systematically. For day outings with standard socks, your usual size suffices. For multi-day treks with a heavy backpack and thick trekking socks, +1/2 size is often more comfortable as feet swell during exertion. Lowa advises trying shoes at the end of the day with the activity socks for a more realistic evaluation.

Measure your foot in mm, compare with the official Lowa chart (note the specific feature 273 mm = 43.5), identify if you need a W version, choose according to your use (day hiking = usual size; long trek = +1/2 size possible). The insole test recommended by Lowa allows you to quickly check if the space is sufficient. If in doubt, take the larger size.
