Hello Aspirant. these hyphens play a very important role when it comes to rank that specific keyword like if you do it this way 'nderarmourfire-basketballshoe' google will look for basketballshoe keyword to rank instead of basketballshoes. Just like you see here best boxing gloves kept all the permalinks with hyphens and they are ranking. SO I will suggest you to do the same thing with your site if you want to up your ranking.
If you need any more suggestions, you are welcome!
