My kids love these shoes
My 3 kids(ages 3, 5, 5) had used various rental shoes and one of the 3 always found some part of the shoe to be uncomfortable. I also found most other kids shoes to have poor to average reviews.
These shoes are awesome. They are comfortable and work well, which means my kids want to go climbing all the time. My kids were instantly more confidant on foot holds vs. using their street shoes.
I love the way the heel strap is connected to the foot strap so that it snugs up all at once. We were able to get the shoes a little big to make room for growing feet and found these shoes to be perfectly snug without being sloppy.
