This is my son's second pair of Tsukioshi's, but we are not new to the brand as my daughter has been wearing them since she learned to walk.  I can not say enough great things about them.  My kids never have any complaints about the fit, they are easy enough for my 1.5 year old to put on on his own and the LAST.  We are yet to wear out a pair despite these being worn all of the time.  In fact, the pair that my son just outgrew look practically new and he's been wearing them for 9 months!  I love that they are washable (I have dried them in a pinch even though the instructions say not to).
