Got it working in the UK.
Interesting app - especially coming from someone who is mostly a climber, and has years and years of ramming my feet into odd-shaped contortionist shoes and finding by intuition that my left foot is about 5mm longer.

Boots
Alpine - 26.5 Hawx Prime 120s's with superfeets and I've not needed a punch on these.
Touring - Struggling. I've been jumping around trying to get heel hold without 6th toe or 5th met pain. I've got wide, but low volume and low instep feet.
Tried:
1. 28 Vulcans with intuition classic wraps (comfortable, but too long).
2. 27.5 Vulcans with stock liners (6th toe punch and met punch, good until the boots just died of old age).
3. 27.5 MTN Explores - great length and width, still felt like foot and ankle swimming.
4. 26.5 MTN Labs with 6th toe punch - good heel hold but I think for long tours my toe will take a bashing the end of the boot too much.
5. 26.5 Maestrale RS's; length feels ok but 5th met pain as soon as buckled (loose as I can get) and I still get heel lift.
Am I downsizing too much? 27.5 / 310+ bsl boots seem to leave me with like a 2cm shell fit.
