One thing I always have a weakness for in tack shops is socks. I love them in all colors and all patterns and if you follow The Modern Equestrian you know I've posted before about how Sock Crazy I am.
JOJOSOX (who happened to sponsor last night's Judge My Ride trivia) is "Made in the USA with CoolMax EcoMade Fibers."
From their website
"In August of 2009, frustrated by socks slipping down, not staying put, and forming holes, Joanna Godwin, known around her "horsey" friends as "JoJo," set out to design the perfect riding sock. Using materials from RECYCLED water bottles, she began working with a manufacturer right here in the USA to create size-specific, performance socks designed specifically for riding boots."
