Just bought some Keen Newport H2 for my son at REI.com for about $25. Limited colors, but he liked the blue. We always pre-buy for the next summer, and this is the best price I've seen this year.
I wish I could pre-buy shoes for my son. he has hit that growth spurt stage where he needs new shoes every 2-3 months, and he is just turned 14 and up to men's 11 already.
