Ce qui se passe dans cette fraction de seconde d\u00e9termine la sensation du pas - et la quantit\u00e9 d'\u00e9nergie conserv\u00e9e. Les mousses sont con\u00e7ues pour ce moment pr\u00e9cis.

C'est la combinaison de nouvelles formulations de mousse et d'un processus de production unique qui rend cela possible.  Leur qualit\u00e9 r\u00e9side dans la restitution de l'\u00e9nergie.

Lorsque la pression et la temp\u00e9rature diminuent, le gaz se dilate dans le mat\u00e9riau. \u201cCela fait mousser le mat\u00e9riau de l'int\u00e9rieur\u201d, explique Matthias. \u201cOn peut comparer ce processus \u00e0 la fabrication de pop-corn. Une pr\u00e9forme compacte est transform\u00e9e en une semelle interm\u00e9diaire hautement expans\u00e9e \u00e0 l'int\u00e9rieur d'une chambre de pression.<\/div>\n   <\/div>\n<\/div>\n<\/div>\n\n\n<!-- row text single -->\n<div class=\"gradientnone\">\n<div class=\"row rowSingleColumnWide spacing\">\n    <div class=\"col articleText\">\n        <div class=\"textStyle_default\" ><h2>Comment notre mousse NITRO\u2122 est-elle fabriqu\u00e9e ?<\/h2>La v\u00e9ritable performance est cr\u00e9\u00e9e \u00e0 l'int\u00e9rieur du mat\u00e9riau. La structure de la mousse d\u00e9termine la fa\u00e7on dont la chaussure r\u00e9agit sous la charge. Les mousses NITRO\u2122 se caract\u00e9risent par une structure cellulaire particuli\u00e8rement uniforme. Elles peuvent \u00eatre fortement comprim\u00e9es, accumuler de la tension et lib\u00e9rer \u00e0 nouveau cette \u00e9nergie. \u201cCes semelles peuvent \u00eatre d\u00e9form\u00e9es jusqu'\u00e0 70 % - comme si l'on pressait un ballon\u201d, explique Matthias. C'est l\u00e0 que la diff\u00e9rence avec les mousses EVA traditionnelles, qui dominent le march\u00e9 depuis des d\u00e9cennies, devient \u00e9vidente. Les mousses EVA sont principalement con\u00e7ues pour amortir les chocs et ont une r\u00e9ponse beaucoup plus lente, ce qui les rend fondamentalement diff\u00e9rentes du comportement de retour \u00e0 haute \u00e9nergie de NITROMC.<strong>\u2122<\/strong>.\u00a0<br><br>Un pas de course se compose de plusieurs phases. Le pied frappe, la mousse se comprime, le corps roule sur le milieu du pied et pousse sur l'avant-pied. Tout au long de cette s\u00e9quence, la mousse est continuellement sollicit\u00e9e. \u201cJe peux mettre beaucoup d'\u00e9nergie dans le syst\u00e8me\u201d, explique Matthias Hartmann. Ce qui compte, c'est que cette \u00e9nergie soit conserv\u00e9e et restitu\u00e9e. \u201cCette \u00e9nergie ne se dissipe pas. Ce que je mets dans le mat\u00e9riau en termes d'\u00e9nergie, je le r\u00e9cup\u00e8re dans une large mesure.\u201d\u00a0<br><br>L'effet est ind\u00e9pendant du style de course. \u201cPeu importe que vous soyez un coureur \u00e0 talon ou \u00e0 avant-pied.

Tant les athl\u00e8tes d'\u00e9lite que les coureurs de loisir remarquent la diff\u00e9rence. \u201cLes coureurs peuvent d\u00e9crire tr\u00e8s pr\u00e9cis\u00e9ment quelle mousse est la plus performante - et cela correspond \u00e0 nos tests m\u00e9caniques.\u201d Ils d\u00e9crivent cette diff\u00e9rence comme une sensation de ressort et de propulsion.<\/div>\n   <\/div>\n<\/div>\n<\/div>\n\n\n<!-- row image multi 1 -->\n<div class=\"row rowImages2b spacing\">\n\t<div class=\"\">\n\t\t<div class=\"row inner\">\n\t\t\t<div class=\"col\">\n\t\t\t    <div class=\"bgimage\" style=\"aspect-ratio:0.8  ; background-image: url('https:\/\/www.puma-catchup.com\/wp-content\/uploads\/2026\/04\/26SS_Social_Run_Deviate-Nitro-4_Q1_Pen-to-Product_03-1.webp'); background-size: cover;background-position: 50% 50%;width:100%\"><\/div>\n\t\t\t\t\t<div class=\"descr\">\n\t\t\t\t\t\tPremi\u00e8res esquisses des chaussures de course PUMA Deviate 4 avec notre mousse NITRO\u2122.\n\t\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t<div class=\"col\">\n\t\t\t    <div class=\"bgimage\" style=\"aspect-ratio:0.8  ; background-image: url('https:\/\/www.puma-catchup.com\/wp-content\/uploads\/2026\/04\/26SS_Social_Run_Deviate-Nitro-4_Q1_Pen-to-Product_05.webp'); background-size: cover;background-position: 50% 50%;width:100%\"><\/div>\n\t\t\t<\/div>\n\t\t\t<div class=\"col\">\n\t\t\t    <div class=\"bgimage\" style=\"aspect-ratio:0  ; background-image: url(''); background-size: cover;background-position: 0% 0%;width:100%\"><\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n\n\n<!-- row text single -->\n<div class=\"gradientnone\">\n<div class=\"row rowSingleColumnWide spacing\">\n    <div class=\"col articleText\">\n        <div class=\"textStyle_default\" ><h2>Interaction avec le carbone\u00a0<br><\/h2>La mousse atteint son plein potentiel en combinaison avec l'ensemble de la construction.

The foam structure determines how the shoe responds under load. NITRO\\u0026trade; foams feature a particularly uniform cell structure. They can be highly compressed, build up tension, and release that energy again. \\u0026ldquo;These soles can be deformed by up to 70 percent \\u0026mdash; like squeezing a balloon,\\u0026rdquo; explains Matthias. This is where the difference to traditional EVA foams becomes clear, which have dominated the market for decades. EVA foams are primarily designed for cushioning and have a much slower response, making them fundamentally different from the high\u2011energy return behaviour of NITRO\\u0026lt;strong\\u0026gt;\\u0026trade;\\u0026lt;\/strong\\u0026gt;.\\u0026nbsp;\\u0026lt;br\\u0026gt;\\u0026lt;br\\u0026gt;A running step consists of several phases. The foot strikes, the foam compresses, the body rolls over the midfoot and pushes off through the forefoot. Throughout this sequence, the foam is continuously loaded. \\u0026ldquo;I can put a lot of energy into the system,\\u0026rdquo; says Matthias Hartmann. What matters is that this energy is retained and released again. \\u0026ldquo;That energy doesn\\u0026rsquo;t dissipate.
