Edit profile fields in front-end

There are a couple plugins i use that add different profile fields for users. For example for a classified ad plugin there is profile field for address, phone number, city etc.

It is quite cumbersome to get a user to register/login in the front-end only to have to go to the backend to edit the profile information.

I am using a plugin to edit the users profile in the frontend at the moment but it doesnt include the additional fields created by other plugins. Is there some way, through PHP or similar, that i can edit these additional profile fields in the frontend?

E.g. User goes to a page where they insert/modify/remove the desired profile fields instead of having to go to /wp-admin/profile.php then back to the site.

Thanks
