used the previous version, from 2021 (GT-2000 9). Version 09 was 13.5, this one is 13 (there are no 0.5 any more), but it looks as being the same size. Good model, as i see there are some changes done to mesh - it looks a bit more durable compare to 9 version (last year it lasted only for 700 km, which is too little for 100$ shoes). This model looks like 2000-8 from 2020 season - mesh is more solid an looks a bit more reinforcedA tongue of of the shoes has been redesigned - better fixation by laces.
