The Line
Three products. Insoles, slides, headbands. We do not offer what we do not print, so the list is short by rule rather than by roadmap — and anything parked, unproven or bought in is not on it.
Every item passes the same test the insole did: **would we use this ourselves, and does the print do something an injection-moulded version couldn't?** If the answer to the second one is no, the honest move is to buy the moulded version and not make it. That question is why this list is short.
Item 01 · Drop 001 · Live
BULL
INSOLES
$99 · lattice comfort, Bitcoin core. A variable-density footbed tuned to your foot, with the ₿ working as a stiffness spine rather than a graphic printed on top of one.
Why print it: a moulded insole is one stiffness everywhere. This one changes cell size and wall thickness between heel and forefoot, per customer, with no tooling cost — because there is no tool.
- Material TPU 95A or PEBA
- Print 11 h 19 m per insert
- Stack Heel 12 mm · forefoot 6 mm
- Sizes US M13 first, more to follow
- Status BEST IN BULL™ eligible
Item 02 · Drop 002 · In the lab
BULL
SLIDES
$128 · recover hard, move easy. Zoned lattice footbed, high heel walls, wide toe box. Supportive rather than plush.
Why print it: a printed lattice lets us tune give by zone, and reprint from the same file rather than replace by a guess.
- Material TPU and PEBA, three-part build
- Print In qualification
- Stack ≈ 38 mm at the heel
- Sizes US M13 first, more to follow
Item 03 · Drop 003 · In the lab
BULL
HEADBANDS
Price TBC · the Bull Button, sewn in. A low-profile TPU badge with the stitch channels printed into the geometry, sewn through technical spacer mesh rather than glued on top of it.
Why print it: a moulded badge is a hard disc on a soft band and it fights the cloth. A printed one carries its own stitch channels, flexes with the mesh, and changes per project without tooling.
- Material TPU 90A button, 3 mm spacer mesh
- Button 20–30 mm, printed
- Assembly Hand sewn
- Open Skin-contact and bond basis — Materials Engineer gate, not closed
The rule
WE DON'T
OFFER WHAT
WE DON'T
PRINT.
There is no fourth item, and the ones that used to be here are gone rather than parked. A water shoe we never printed, a heel cup sitting behind an open question about its own cut line, a headband our own copy admitted nothing on our floor could make — none of that is a product, it is a plan with a price next to it.
Three is not a launch strategy. It is the number of things we can print, inspect and stand behind today. When a fourth earns it, it gets a drop number that never resets and never skips.
Custom Bull
From $240. Not a fourth product — the same three, with your mark engineered into the lattice. Team, shop or brand. Sample first, run second, and the run does not start until you have held the sample. It is the clearest proof that a BullPrint is geometry rather than a print laid on top of a product.
Bull-Grade
A joke that turned into a spec. Bull-Grade is our qualified materials list, and it is short on purpose. We print nothing else. If a product needs a material outside this list it needs a qualification run before it can be sold — a bench decision, not a marketing one.
| Code | Material | What it is for |
|---|---|---|
| BG-01 | TPU 95A | The firm one. Footbeds, insoles and anything that has to hold an arch under load. |
| BG-02 | TPU 80A | Suspended. The machine vendor's own guide says 85A and softer should not be fed through our extruder at all, so this was listed as qualified against hardware that will not run it. It comes back when a coupon proves otherwise, not before. |
| BG-01b | TPU 90A | The skin-contact one. White is doctrine, not preference: a white part shows dirt and wear immediately. Bull Button and any wear surface. |
| BG-03 | PEBA | The performance material — lighter and springier than TPU. Listed, not yet qualified on our machines: no coupon has been run for it. Nothing ships in it until one has. |
Two entries here are honest about not being finished, and that is the point of having a list: qualifying a material and wanting to use it are different decisions, and only one of them is ours to make by deciding.
Four finishes
Gold is the signature and stays the hero — insoles ship in it. Three supporting finishes let the slides read as everyday footwear rather than trophies.
| Code | Finish | Where it goes |
|---|---|---|
| CW-01 | Gold | The signature. Loud on purpose. Insoles. |
| CW-02 | Graphite | Equipment finish, matte near-black. Slides. |
| CW-03 | Bone | The contrast run. Limited only. |
| CW-04 | Titanium | Industrial grey for premium runs, in PEBA. |
One finish per object. No two-tone prints, no colour-change gimmicks. Where a bull mark needs to contrast — a gold bull on a black slide, a black bull on a white one — it is printed as its own part and seated flush into a pocket, so the two colours are two prints that never meet on one plate.
Bitcoin orange is a filament we do not stock. ₿ appears as geometry, never as a colour.
<p class="pull">Rainbow, silk, glitter and colour-shift filaments print beautifully and make the object look like a hobby print — which is the exact impression this whole brand is built to avoid.</p>
Three drops, not a catalogue
A full-catalogue launch reads as a dropshipper. Three drops read as a lab with a point of view. Each one gets its own week, its own story and its own verdict.
- Drop 001 — Bull Insoles. Live. The thesis: a lattice tuned per foot with
no tooling cost, because there is no tool.
- Drop 002 — Bull Slides. In the lab. Three printed parts, no adhesive in
the load path.
- Drop 003 — Bull Headbands. In the lab. The Bull Button sewn through
spacer mesh, with its materials gate still open.
After that: reprints for worn pairs and custom runs on the same three. Owning the file is the whole advantage — a worn pair is a repeat order rather than a lost customer. There is no wave four written down, because writing one down is how a lab talks itself into a catalogue.
Editions stay small because we choose to, not because we can't print more. That distinction has to stay true or the scarcity becomes theatre.
What we won't sell
Anything carrying a safety burden we can't back with testing. No orthotic claims, no protective footwear, no climbing, no safety toe. A footbed that fails is an uncomfortable afternoon; those other things fail differently. The line is there on purpose and it does not move for a good quarter.
<p class="note">Only Bull Insoles can be bought today, and that is on purpose: slides and headbands are in the lab, and a button that takes money for something we cannot print yet is the one thing this whole page is arranged to prevent. Prices are in USD. Card, Cash App Pay, Klarna, Link and Amazon Pay at checkout — whatever is enabled on the account shows up automatically, because the session does not pin a payment method list. Every item is made to order — nothing on this page exists in a warehouse, which is why the print hours are listed next to the price. BEST IN BULL™ is issued by a person at inspection, never by the checkout.</p>
