I really like mine I have the Classic and KSO. I really have had some issues with the classics where blisters are concerned but I may not have given myself time to get used to them before I took a 6 mile walk in them. I really think my KSO's are a better fit for me because I have very narrow feet. As time goes on I will be doing different things with them. I am taking them to WY. and plan to use them in the streams and hope to fish in them if they are not to slippery.
