If your heel slips excessively during the hiking, it means that you have too much interior volume at the top of your boot. The Surgeon’s Knot (or Double Overhand Knot) technique allow you to adjust the tightness of the laces and to maintain constant tension at the points where your feet feel too loose. So, your foot may move naturally — without causing any excessive pressure or blister-inducing irritation.
This technique is usually suggested for who have narrow or flat feet.
How to do:
1. Lace your boots in the traditional way until the blocker hook you find in the metatarsal area on the top of your boots (or the point where your feet feel less pressure) and make sure that the laces over this are pulled snug;
2. Make the surgeon’s knot by wrapping the laces around each other twice and pulling them tight;
3. Thread the laces through the next eyelet to lock in tension from the knot;
4. Repeat the surgeon’s knot again after the next eyelet;
5. Thread again the laces through the next eyelet to lock in tension from the knot;
6. Continue lacing your boots with the normal diagonal lacing pattern.
