By greasing the instant of my Oakley leather walking shoes (like Ranger but without the weight or blisters that often come with it - :) give a look to the comment Stéf02820 on this page:) - and support the foot where it's needed ... a publicity stunt for those that would interest and who do not know [...] *, I wondered with trepidation if the product I used was the DE grease seal (like the one we used at the time when the ski shoes were leather and where we had little choice) or fat of a company named LE Seal. I have not found the answer on the site. True, I have not sought too since I unearthed in the words of those who moan because the fat is not THE seal fat OF seal. About me, I hope they know what they are talking and that it is a synthesis of fat. Poor seals! Let the so quiet in a time when we know how effective fat synthesis, that of THE Seal being a perfect illustration. For years I used happily.
* Update a few days later. I put a link leading to Oakley and I made myself the 'squeezer'. If you are stuck, enter at Amazon Oakley boots' and you will see these gems who certainly are not a gift but it must do well 5 years I used; they are still nickel.
