If New Balance are working for you, then there is no reason to switch. Good for you if you feet don't hurt after days of park touring in them. I have tried so many different kinds of expensive athletic shoes, including New Balance. My feet would hurt so badly! And, speaking of blisters, any athletic shoes, etc. tear up the back of my heels with bleeding blisters.
But, since you asked, I love my
Crocs. They don't usually rub blisters, but they could if they didn't fit right, and rub on my skin. THey don't make my feet sweat, and I don't slip on wet surfaces, as long as they are not old worn-down crocs.
I have spent (wasted) lots of money on other brands that were supposed to be so good for me. I have Merrills which I can tolerate for a little while, only if I wear my Croc inserts with them. I have tried on Dansko clogs several times, and it feels to me like walking on concrete. Ouch! I have several pairs of Clarks, which I consider my dress shoes. So I can wear them for a little while, but not too long. I just bought some Fitflops on clearance to try out, but I'm not sure they work that well for me all day.
THe point of all this is that I would love to find a shoe that I can wear all day like I can with Crocs. I get so frustrated when people, including doctors, claim Crocs are so bad for your feet. Offer me an alternative that does not cause me unbearable pain after several hours, and I would be willing to switch from crocs. All I know is that for my upcoming trip all I can even imagine wearing every day are my several pairs of Crocs.
