I got Yanko Chelsea boots on the 915 and I'm wondering what the intended fit is. The shoe feels about right in the forefoot are, acceptable in the heel.
At ankle height the there is space front and back between the upper leather and my foot/leg. Left and right the elastics only touch my foot.
The uppers only fit my instep in the lower part.
Is this acceptable? The size feels right in most areas except from the upper part of my instep to at ankle height, I have only minimal heel slippage and otherwise don't slide around in the shoe.
How are Chelseas meant to fit?
Maybe you should try some other last or just go bespoke as said before.
