Rechargeable Heated Socks for Men & Women - 7.4V 2200mAh Battery-Powered Winter Warm Socks for Cold Weather - Perfect for Hunting, Skiing, Camping & Outdoor Activities

I bought these because they had size medium. I wear an eight to nine woman's shoe.They are gray ,not my friend choice. I realized that I only wear them around the house ,so why cares?The fit is perfect,plenty of toe room.They stay up nearly to my knees as long I wear them.The heating element warms my toes to my instep. I keep them up on low 90% of the time. It feels as if nothing is going on , it's like I just have a cozy warm pair of socks on and believe me I tried every kind of sock and they didn't do this. I am so satisfied and I didn't didn't want to write a review until some time went by,even though I was happy the first time I tried them on. By the way way, the battery on low is as promised,I put them on at 2:00 and take them off at 10 or 11.
