If it were up to me, we would never have to wear shoes and socks. I love the summer for this very reason. The kids can throw on their flip flops, and we're good to go. But, as the children must wear shoes and socks to school, we have a little system that minimizes lost and mismatched socks.
A small net bag hangs on our laundry room door. The kids take their socks off as they come in the door and put them in the bag. Now they are all together in one place waiting to be washed, instead of strewn around the whole house or hiding under beds.
I still prefer flip flops, but this has made sock season more manageable.
