With great efficiency comes great risk.

No protection from plants & stray robots, but did manage to not get any blisters or chafing.  Had to loosen the left paw, as its knots dug in again.  This lace configuration has been the easiest of them all on the paws.  Threw down at 7m45s/mile for 5 out of 10 miles.

Replacing the 1/4" rope with double layered 5/32" would be the next step in durability.  Mixing different string varieties looks very native, but isn't affordable.

After a 12.2 miler, the current lacing proved to have the right idea.  No knot is required under the toes.  Move the yellow knot down the side so it isn't directly on the tendons, get the tension right, & there are no showstoppers besides underside wear.  Left the green knot over the tendons so it would pull the toe section inside.  

The underside might wear faster because sandals for the unnamed gender are too narrow & the rope is pressed down by washers.  Fortunately, they had men's sandals in stock 1 more time.

Sandals replaced shoes for 35 miles of the last 47.  With no more of the same blistering that shoes caused, 8 years of callousing will soon go away.  There won't be any going back to shoes.

During another 12.9 miles, finally had the 1st heat wave of the year, the sweat came down, & a new blister formed.

Definitely glow rope, tightness, & much climbing, but the right paw was still golden.  The glow rope must absorb sweat, salt & become like sandpaper. 

Sandal pair #2 now has 35.4 miles.  Sandal pair #3 now has 31.75 miles.  The laces have been replaced, every 10 miles.

It's been a long process of getting used to minimal paw wear, for ever higher speeds & longer distances.  Originally, lions didn't even know if toe plugs would work.  It's about time to invest in something proven to work.
