I love these booties so much. I bought them for a heavy walking trip last month (45 miles in 9 days), and they were absolutely perfect. I never had a blister and the cushion insoles gave my feet lots of forgiveness. I have high arches, so I did add an additional foam insole with more arch support for long walking days, but I've worn them without it too and I just can't say enough good things about them. Really great buy.
