how do i modify the url

HI there I have installed the latest version of wordpress and wanted to know how i can modify the urls.

I have setup a category and sub category

Category: clothing
Sub Category: red socks

Currently my domain looks like this;

https://www.domainname.com/category/clothing/redsocks/

But I would like for it to look like this;

https://www.domainname.com/redsocks/

Is this something that I should set under Permalink Settings.

Currently under Common Settings under Custom structure I have the following;

/%postname%/

Cheers
Malcolm
