It was with a small amount of reservation that I purchased the inner soles on the 15th September 2005. Would they work for me? I only had a week to get used to them before our trip up Mt. Kilimanjaro. Was I doing the right thing? I followed the instructions on how to get used to them in my shoes – it was a little uncomfortable at first as you said. By Wednesday the 21st I wore them for almost a whole day. My feet were quite tender so I gave them a break for the next two days. I would wear them again on Friday 23rd on our trip up to Johannesburg and the flight through to Kilimanjaro. Not being on my feet all day, they were fine. I didn’t wear them Saturday – as we were just having a quiet day at the hotel. Then Sunday it was time to set off on the first of 6 days hiking. Now was the test! We did a 6 hour hike through the rain forest up to our first camp. And I had no pain in my feet. I was now convinced that they were working. The next question was would I be able to wear them again the next day. I hadn’t really worn them 2 days in a row for any length of time. I did, and again they were fine. Now they were a permanent part of my hiking boots. What I’m really saying is that the inner-soles made my trip a success! We reached the summit of Mt. Kilimanjaro on Thursday morning with great jubilation. I would like to thank you for your time and congratulate you on a great product.
