Soled 3D printed shoes

A tougher underside adds protection from water, dust and daily ground contact.

Taka

The thin-soled version of Tora: the same small-grid barefoot idea with a fine sole added for more ground protection while keeping the upper light and breathable.

Tryton

The thin-soled version of G0: the same 45 degree, toe-down grid logic with a fine sole added underneath.

Due

A simple watertight River shoe with a direct, functional shape. Due keeps the printed form cleaner and more protected than the open breathable models.

Yume

The thin-soled version of Mirai: the same 45 degree, toe-up grid logic with a fine sole added underneath.

E7

The thin-soled version of Aspys. Like Aspys, E7 prints vertically as a mirrored pair fused at the collar, then the two shoes are separated with scissors after printing.

3D PRINTED SHOES

Are 3D printed shoes actually comfortable?

The honest answer: they can be comfortable, but only when shape, TPU hardness, sizing and first-wear expectations all line up.

MATERIAL GUIDE

TPU for 3D printed shoes: 82A, 85A, 95A and what changes on foot

A practical guide to softness, durability, print difficulty and why harder TPU can print well but feel worse.

TPU SHOES

Can you 3D print shoes in TPU?

Yes, but the result depends on TPU hardness, layer bonding, shoe geometry and how honestly the first pair is tested.

FIT GUIDE

How to choose the right size for 3D printed shoes

Foot length, toe room, EU sizing, socks and why scaling a shoe file is not the same as choosing a size.

CUSTOM SHAPE

How River custom shape is generated from two foot photos

The paid custom flow uses one top view of both feet and one side-profile photo of one foot so the shoe geometry can be adjusted manually around a real foot.

SOLE & GRIP

Do 3D printed shoes have grip on wet floors?

The grip question comes up constantly. Here is the realistic difference between TPU texture, dry floors, wet tile and adding a thin sole.

Barefoot 3D printed shoes

River’s best barefoot pattern for comfort and durability: a smoother inside surface that can be worn without socks, generated from direct Grasshopper toolpaths with interleaved semicircular curves per layer.

Air purifiers

Roy

A quiet, USB-powered air purifier that just does its job. Cleaner room air from a printed object that actually looks like it belongs on the shelf — no humming appliance, no exposed electronics.

Ice air coolers

Yuki

A full-size ice-pack air cooler built from printed parts, a quiet USB fan and a frozen water pack. Freeze the pack overnight, place it inside, and Yuki sends a steady cooler stream across the desk with very low power use.

Water filters

Jem

A polypropylene tap water filter for activated carbon. The flower-like top opens for filling, the body attaches to standard taps, and the bottom grid holds carbon while water passes through. Joined G-code keeps the water path cleaner by reducing micro-stringing.
