Yep followed instructions, several times i heated them tried a number of ways to get them to fit better, many people are happy with them I can only give my experiance of them and I thought they were all hype, others may well be very pleased with them. My problem with them is they market them as being heat mouldable to fit any foot, even though they won't fit when you buy them, well try sending them back after you have realised you can't get them to mould to your foot, like I said zero returns policy and after sales service is also a point blank no refunds or returns from them once you have heated them up.
