New Boots - Terrible Heel Blisters....

I finally sprung for a new pair of boots. Purchased the Asolo PW Matic 250NBK from REI. http://www.rei.com/webservices/rei/DisplayStyle/780797?source=19113&cm_mmc=aff_cj-_-datafeed-_-product-_-na&mr:trackingCode=58C7FE5D-0319-DE11-B4E3-0019B9C043EB&mr:referralID=NA&siteId=cjIsd2x-it3792&URL=http%3A%2F%2Fwww.rei.com%2FOM%2Fstyle%2F780797%3Fcm_mmc%3Daff_cj-_-datafeed-_-product-_-na%26mr%3AtrackingCode%3D58C7FE5D-0319-DE11-B4E3-0019B9C043EB%26mr%3AreferralID%3DNA&PID=1070188&AID=10456937&cm_mmc=CJ-_-Aff-_-1070188-_-10456937 They felt good at the store and I felt like I had sufficiently broken them in going on various 10 to 30 minute walks/hikes and wearing for a couple weeks at work. Well not but a mile into hiking Pikes Peak I was feeling a hot spot on my right heel. It was the incline (not ”the incline” for you locals – but the steep grade of the trail) that was creating the friction. I immediately stopped and dressed it with moleskin, dried my mid-weight smartwool socks and continued. It only got worse and about 3 miles into my hike the left side started doing the same thing. I wear a size 14 and a 13 is just too small. Half sizes stop after 12. So if the issue is a size problem I'm screwed. After camping at Barr camp I decided to double up my socks to two mid-weight smartwools. The hotspot on my left heel soon went away. I think I did too much damage to the right though – as the pain continued and by that morning already had a small blister. Should I take them back to REI or keep trying with different socks/liners? Or should I be having this discussion with a saleperson at REI? Any suggestions would be much appreciated… Do you think I just have the wrong boot – as I have read on some of these blister threads?

Thanks, Will
