Thanks for the help.
I'll have a look at some lace-ups but I've pretty much always worn velcro/slippers and not had issues before so I'm hoping I can stick with them for the sake of laziness.
I'll check out the TN Pros too, I should've said I was looking at the Flagship LV as I had heard that the standard Flagship has a higher volume than the Instinct. Is the TN Pro not a lot stiffer than the VSR?
Will have to get down to Outside to see what fits.
Lace shoes are 1-2 seconds more faff than velcro, don't sacrifice a significant difference in fit for the sake of some idealised 'speed'. It's missing the point entirely.
