I was given the DX of Planter Facititus sp? in the year 2001, & after going to extreme lengths, to seek a solution, literally thousands of US dollars during a 2 year time frame, as I am Male Height 6'1" weight 180/184 lbs, 1 chiropractor (whom I deeply trusted) and, multiple Reflexology professionals (from USA well known SPA'S in CA/AZ/NM/ + Los Cabos & Puerto Vallarta (both in MX), A to Z of shoes, age early 50's I finally lucked out on this AFAIK "Statesville, North Carolina" sock mfg, called "Thoros" with excellent customer svc, + a retail shoe salesperson, whom I trusted also, I have used Thoros thick padded socks, now for over 20 years successfully. IMHO, Use them even instead of bedroom slippers. Note: Thoros do have different types of padded socks, some thicker than others, I recommend to just get the thickest ones. Also, if I may add, I have a walk-in closet full of so called designer shoes, I rarely wear, as I am now over age 70 years old, the only shoes I have also worn also, the past 10+ years, have also been ECCO TRACK II low rise waterproof shoes, with a very thick heel, used by many serious hikers. My understanding from my formers travels to USAF & US Army posts in Germany, I also found lots of THOROS socks for the USA military, imho, a large customer of Thoros. Bottom line: my feet never hurt me no more. Size tips? I always order the 10-13 range, my shoe size is a 11 1/2 EEE (US) or size 12 (UK). I suggest one may need 1 size up, shoe size, due to the very thick texture of the complete sock.
