https://www.amazon.com/Silicone-Cracked-Heel-Protectors-Sleeve/dp/B078GJ6FR8?th=1 These heel protectors are cool. What a difference they made. They are made of silicone, so you can imagine just how good they on your heel when you are used to walking around in pain due to foot problems. They are easy to put on and can be worn comfortable in most shoes. They are anti-slip and sweat absorbent for the ever so popular, sweaty foot. Thank you #FOOTINSOLE #RankBoosterReview #Sponsored
