These adjustable sock blockers are great for knitters who frequently wash and block socks. Sold in a pair for you to assemble, they are adjustable at the the leg, foot, and heel to ensure the perfect fit. These sock blockers are just the thing for finishing up any sock knitting or sock crocheting project. Once the pieces are assembled using the included two-part screws, the sock blocker pieces can slide to adjust. This means you can get more "in between" sizes, since you're not limited to assembling them where the holes meet. You no longer have to take them all the way apart to adjust for blocking different pairs of socks.
