A pair of white and blue Lotto Zhero Gravity football boots, from the 2000s, which are boxed and come with an accessories pack including spare studs (12 in total in three different sizes), a special stud key which doubles as a shoe horn and 2 pairs of interchangeable insoles (one pair already in the shoe). These are the first laceless football boots to be manufactured. Upper - Special lightweight, water repellent, anti-shock microfibre upper, it has pro-fit technology to ensure perfect fit to the shape of the foot to allow maximum sensitivity in controlling the ball. Sole - Pebax and TPU sole made up of 7 fixed blade-shaped studs to enable excellent differential grip and 4 interchangeable conical studs to ensure maximum stability. Stud - New-generation interchangable studs. Lightweight, you screw them in and out in just one movement. Insole - Interchangeable insoles with a special Poron anti-shock insert to improve shoe fit, regular insole for a standard fit and slim insole with a fuller insert for a closer shoe fit. The Zhero gravity boot was launched for the 2006/07 football season and was developed at the Lotto research and development centre as part of a project that became known as' Project Zhero'. Poron (R) is a breathable material with an open cell structure that has the ability to absorb a measure of moisture from the active foot keeping the shoe and the foot dry. The material offers more shock absorption than other materials giving good support to the joints all the way up the leg. It is made without plasticizers so it will not shrink or become brittle and crack with age.
