My daughter loves these sandals. This is actually her 3rd pair! The only thing I would suggest is to go up a size, or if they have chubby feet I would go up 2 sizes. I always go up a size in roxy sandals, but these specific ones seem to have a more narrow strap. One size up fits her perfect, but if I were buying this brand for my son, I would go up 2 sizes due to his chubby feet. Going up 1 size doesn't really make a difference in my opinion, she wears a 1 and I ordered a 2-3. With a size 2-3, her feet fit front to back on the sandal so I could've easily went up a second size. These are not your average thin, junky material flip flops, roxy flip flops are durable and made very well. My daughter always outgrows this brand before they tear up or fall apart unlike other flip flops I've bought for her.
