Hello @Milikeleka. Trekking poles are a must have piece of gear! 

Here is a great article to get you started on How to choose trekking poles. There even is a short video for you to watch too! 

If you are still unsure what you should go with you have 2 options:

-Visit a local REI store, where an employee will be happy to help you pick the right one for you.

-You can book an appointment with Virtual Outfitting

I hope you find the right Trekking pole for yourself and you  are able to put it to quick and great use!
