Amblers Safety FS116 Hardwearing Pull on Safety Dealer Boot

I am size 7.5 usually. I bought a size 7 and it was massive! Could have Easily bought a size 6. If they were laced I wouldnt mind so I could tighten them but they are slip on so my foot slides around in the boot. Have been wearing these for 1 week on stage and the inner sole has worn a bit already. A good convenience steely though, they do the job protecting my feet and are easy to slip on and off for work.
