Lightweight shoes for backpacking?

“I have these shoes I use for dayhiking:

Solomon XA Pro 3D Trail

I can easily 6-8 miles and my feet don;t really hurt with up to you know, 15-20 lbs. Question is, any of you try and backpack for 2-3 days with shoes this light? They have a medium-stiff sole to them, but when i get weight on them i don;t know if they will kill my feet. Any experience?

BTW, I have a pair of Montrails I use for longer treks but I want to try and save weight.”

“A NOBO thru-hiker that I ran into on the AT two weeks ago in VT has been wearing that exact same shoe since he left GA. He's on his third pair ~ Solomon has a one year guarantee and he was putting aboot 500 miles on each pair, he said. Only reason I remember it is because I had done some trail magic for him in PA and then saw him again in VT...he talked about his shoes both times. He loves them.
Hope that helps a little.”

“Many of us, myself included, backpack almost exclusively with trail running shoes. No problems.”

“Looking at keen taos hybrids right now.
Put tons of miles on some cheap new balance 470's took everything and more(im not small)
current hiking tennie is a pair of dunham wafflestompers.. not the lightest, but freakin awesome.”
