After four or five hours, you started to feel tired and things started to feel difficult. Even though there were still nearly ten more hours to go! Keeping going until the evening was absolute agony. But really it was all because of my feet.
Some friends recommended the kyBoot to me. Then I tried out my first pair and was satisfied, but I was even more satisfied with the second pair. It's much better, and I can really enjoy myself now, even in the evening after all those hours.
