I wear trail runners for hiking and trail running on rugged terrain with elevation gains of plus/minus ~1,500 - 3,000 feet and 3-9 miles roundtrip.  I previously bought the Salomon Women's XT Wings 2 W Trail Running Shoe. I loved those shoes.  I had to change out the insoles after buying them but other than that had no feet issues.  Once those wore out I bought this shoe thinking it would fit exactly the same but they really hurt my feet from the start. I am a neutral runner and immediately had pains on the outside of my feet and along side my arches, plus in my calves. I continued to wear these trying different types of insoles to correct for the pain until I ended up with a foot injury that was probably aggravated by the poor fit. Needless to say, I'm looking for new trail runners. I will still buy from Salomon because overall they have excellent grip on rocky and gravelly surfaces, and great agility.  The shoes are well made with rugged soles and toe protection. I only wish they would come up with a different method of laces.  I have Salomon rollerblades and for me, this brand never has great arch support so I end up swapping insoles and find the shoes comfortable afterwards.
