I had a pair of Scarpa Kailash fitted size 39 and off to Everest Base Camp in 10 days. Just yesterday I went to a podiatrist as just recently developed alot of blisters only on heel of left foot.Am disappointed as professionally fitted but he told me they're too small. Am looking at a pair of Scarpa Mustang size 40.5 would these be appropriate for such a trek if usuaally size 8-8.5. Desperate and stressed now.
I just trekked to EBC a few months ago, and honestly you'll be fine with just about anything. It's not that cold during the day, so you could even get away with tennis shoes. Hope this gets to you in time.
