I hiked a ton of mileage over 4 days in the grand canyon in my trail runners. I think I choose poorly,but learned some information on my feet as they are small in size… I will admit finding the right shoe for me is really tough…and usually my feet just hurt.
As i was coming out my feet really HURT! and i had a couple blisters.
Upon reflection and pouring out my shoes with the sand from this hike that was one of the problems. Any suggestions here I took them off and poured out the sand, but just kept being met with more sand. I was making good pace with my pack @ 3.5 mph…this however led to blisters imo.
Feet hurting.. Did i need more support or more cushion? I think the swell from my feet from the shear amount of mileage made the shoes not wide enough which made it tough to pack out
i will be doing 10-12 mile hikes with weight to prepare for multi-day long mileage goals.
