TPU Runners US 10.5

The Lattice Runner is a modern, sock-style running shoe that comes off the printer in one piece. The midsole is a gyroid lattice that cushions, flexes and shows through side windows, while a solid outsole with a chevron tread and a flex groove gives you grip. The upper is a thin, breathable shell with diamond vents, two cross straps over the midfoot, a reinforced heel cup, a thicker collar edge and a heel pull tab.

Features:

• Supportless, single-piece design that prints sole-down

• Gyroid lattice midsole, about 22 mm deep at the heel and 14 mm at the forefoot

• 27 mm heel stack, 19 mm forefoot stack and an 8 mm drop

• 12 mm toe spring and a rocker profile for a smooth stride

• Chevron tread pattern with a forefoot flex groove

• Vented upper with a reinforced heel counter and pull tab

• Mirrored left and right files included

Size: Built for a US men's 10.5, which fits a foot about 277 mm long and 104 mm wide at the ball. Each shoe measures 299 × 122 × 106 mm.

Fit tip: Trace your foot and compare it to the size above before you commit to a long print. You can test-print just the bottom 30 mm of the shoe to check length and width first.

Print settings:

• Material: TPU 85A–90A recommended (95A works but feels stiffer). Dry it before printing.

• Nozzle: 0.4 mm at 0.2 mm layers, or 0.6 mm at 0.3 mm layers for faster prints

• Speed: 20–30 mm/s, with slow, short retractions

• Walls and infill: 2–3 walls, 100% infill (the lattice is built into the model)

• Supports: none. Print sole-down as oriented.

• Adhesion: a 5–8 mm brim

• Temperatures: nozzle 220–235 °C, bed 40–50 °C

• Bed size: needs at least about 300 × 300 mm, placed diagonally on a 300 mm bed

• Material use: about 445 g per shoe (estimated)

• Print time: about 20–28 h per shoe with a 0.6 mm nozzle, or 35–50 h with a 0.4 mm (estimated)

Notes:

• Expect a little stringing in the small vents, which cleans up easily.

• There's no insole built in, so an aftermarket insole can add comfort.

• This is a hobby print, not certified athletic footwear. Break it in on short walks first.
