Love, love, love this brand!  Tsukihoshi shoes are super light, super comfortable (especially for kids with wide feet), and washable.  My children have worn Tsukihoshis every summer for the past five years.  Have your feet ever felt hot inside your shoes on a warm day, and because you have hot feet, the rest of you is hot?  Because they are made with a lot of mesh, these sneakers are very breathable, so that won't happen.  I can't say enough good things about these shoes!
