Whether it's clothing, shoes, or poles, when ordering online, it's not always easy to choose the right size. Don't worry, you can easily determine the size of your trail poles using the following formula:
your height in centimeters x 0.68 = pole size
Example: I am 1m75 tall
175 x 0.68 = 119
So I choose 120 cm poles.
The poles will be roughly 2/3 of your height.
In the store, you can of course try on the different sizes and choose the one that best suits your feeling.
At the start, on the flat, your elbow should form a 90° angle and your forearm should be in a horizontal position.
