Can anyone comment on how much thinner the olfe is compared to the hiro last? My double monks on the hiro last had a bit of heel slippage (which I remedied with a tongue pad). However, my CTBs on a supposed wider last (ama) fitted well. I suspect the hiro would be OK on a traditional laced oxford though.
I've obviously seen the meermin last chart but I'm after someone who has worn both if possible.
