I found that my feet were getting sore after being on the boat for a full day. Much as I like my Xtra Tuff boots, they don't have squat for insole support. So, I bit the bullet and stepped on one of those Dr. Scholl's Custom Fit machines in the local Walmart. $49 for the recommended insole. Wow! What a difference! Feet don't get tired and sore after a day of fishing anymore. YMMV... I have no affiliation with Walmart or Dr. Scholls, I just like comfortable feet!
