I’m normally a uk10 but went for a uk10.5 as I thought would be a bit roomier, but actually these fit really snug. Strange sensation walking with the pads on the sole, kind of nice. Very easy to stick your foot in, no bending down or anything, it’s like slipping your foot into a slider. The structure around the heel opening is chunky and strong enough to not collapse. Looking forward to slipping these bad boys on every evening after doing 30k steps round theme parks all week.
