I don’t find my carbon fibre soled disco slippers prevent me getting into the back of beyond or down the gnar.
I ride BMX on flats and I’m happy to DH or MTB on either. A few years ago I spent 6 months on flatties as an experiment, but I was happy to come back to SPD’s for the extra efficiency and control. Plus… even my disco-slippers grip better when walking in the mud and on rocks than fashion skate shoes 🙄
I’m half tempted to repeat the experiment with some 5:10’s… but I’m loath to buy new shoes and pedals as I’m not not sure the outcome would be any different to last time. My mate who broke his ankle last year and is on flatties now is looking forward to getting his SPD’s back, and he is a very good Mega/DH-Enduro type rider. I do see the flatties thing as a bit of an MTB fashion thing at the moment – but so what? The only things that do make me laugh are when people people fall over when trying SPD’s for the first time… or when skate shoe wearers complain of cold wet feet while us winter booted SPD riders have warm toasty toes… ooooh it makes my sides ache to think about these things 😆
