Hi there, since now I always used Yonex shoes on court (SHB-98 and SHB-68 european size 43). Unfortunately the new SHB-100 I bought 1 week ago do not fit my feet, because of this stupid lateral claw system (after 10 minutes on court it begins to hurt like hell and i definitely can feel the two lateral claw plastic stripes within the shoe dig into my feet). So now I am looking for alternatives and searching the www I came across the Hi-Tec 4Sys badminton shoes. I really want to give them a try, but since my badminton dealer has to order them himself it would be perfect to know how Hi-Tec shoe sizes compare to Yonex shoe sizes. I hope someone can provide assistance Thanks in advance Alex
