How much space should be in front of the toes?
Enough for swelling and descents without allowing the foot to slide; the incline result matters more than one measurement.
Why do toes touch only downhill?
Excess volume, weak heel hold, loose instep lacing or insufficient shell length can cause it.
Should boots be sized to the larger foot?
Use the larger foot as the minimum requirement, then confirm the smaller foot remains controlled.
Can lacing prevent front contact?
It can improve heel seating but cannot create missing shell length.
Put the advice into practice
Late in the day, wear trail socks and descend a ramp ten times; reject repeatable front contact on either foot.
Limits and cautions
A thumb-width rule cannot account for toe shape, boot shape or forward slide.
Toes should remain clear downhill while the heel and midfoot stay controlled.
