my answer to the question about the 5-10 insoles is to throw them away and get some decent insoles. the originals roll up or slide because they were crummy insoles to begin with. the waffle design holds water and sand and were too thin and sleazy to begin with . they offered very little padding or impact resistance- woefully needed dut to the thin soles in the 5-10. i stuck a pair of shock doctors insoles in my 5-10s and they are much more supportive, and add to the padding for the foot, as you walk on rocky streambeds, and they don’t slide or roll up like the standard footbeds did.
