I have 2 pairs of the Go Walk 2s that I wear for at least 14 hours per day. Each lasted me about 6 months. Instead of paying the same price for another pair of 2s I decided to try the 3s. I wish I hadn't. The 2s fit from the get go and seemed to offer better arch support. The 3s with the &#34;goga&#34; foot bed is not better for my feet. I will go back to the 2s until I cannot find them anymore.
