I changed in my Xcel booties a while back for these 5 finger ones by Vibram. I did it because the sole is thicker and gives more protection against sea urchins and sharp rocks. The razor cuts in the sole also give excellent grip. Now that I’m used to the 5 toe feeling, other booties feels uncomfortable. They feel like putting a sock on your hand versus a glove. I also seem to get better feel with these on as they are probably the closest I can get to bare feet. An added benefit is that I notice that my feet cramp a lot less. I like them so much that I bought some to wear on land instead of my crocs.
