This is the closet for black-cinder days: Sunset Crater’s Lenox Crater and Lava’s Edge loops near Flagstaff, plus cinder-cone climbs like Inferno Cone at Craters of the Moon. The thesis is abrasive grip and a sealed collar — NNormal Tomir 02 with Vibram Megagrip Litebase — plus gaiters against scoria grit, sun coverage for reflective dark rock, and a Watch Desk that pairs a durable trail computer with a Christopher Ward C63 Sealander on rubber.
It is not Soft Sand Desert Run (flotation on dunes). It is not Sedona Red Rock (Megagrip sticky on slickrock). It is not Technical Rocky Trail (granite scramble and poles). Cinder volcanic trail run is loose scoria, ash, and sharp basalt — where you dig for traction, keep grit out of the shoe, and respect heat radiating off black rock.
Note.
Confirm current pricing at the retailer. Stay on designated trails — NPS protects fragile volcanic landscapes. Carry more water than the mile count suggests. Links go to the brand + model when available.

Running on cinder cones and lava fields
“From a distance, this lava field looks like dirt, but they are anything but dirt, being made up of jagged, hard rock.”
UltraRunning Destinations — Volcanic activity, running on cinder cones and lava fields (Big Island, Hawaiʻi)
UltraRunning Destinations’ Big Island field notes treat lava and cinder as their own surface problem: not soft-sand flotation, not sticky slickrock — jagged basalt and loose volcanic tread that punish a casual shoe choice. Pair that with gaiter discipline on sharper volcanic sections, where rock fragments enter low-cut shoes fast.
This kit leads with NNormal Tomir 02 — Vibram Megagrip Litebase and a durable upper for abrasive miles — plus UD FK gaiters so scoria stays outside the collar while you practice careful footing on loose cinder.

From the field
Volcanic days fail when grit fills the sock and the outsole cannot bite loose scoria. Short cinder-cone charges still want sealed collars; longer lava-edge loops want flask volume and sun for reflective black rock.

Lenox Crater Trail
“Use caution when hiking: lava is brittle, unstable, and sharp! … Lenox Crater Trail … Distance: 1.6 mi (2.6 km) round-trip … Moderately Strenuous.”
NPS — Sunset Crater Volcano National Monument · Hikes and Trails
Arizona cinder practice without inventing race stats: a marked Lenox Crater climb through ponderosa with views to Sunset Crater, the Bonito Lava Flow, and the San Francisco Peaks. NPS also notes Lava’s Edge — loose cinders and rough basalt along the flow edge (3.4 mi round-trip, moderate). Stay on designated trails only.

Inferno Cone
“Trail surface: Gravel-like cinders … The steep trail to the top of Inferno Cone is challenging … Temporary obstructions may include … loose cinders…”
NPS — Craters of the Moon National Monument & Preserve · Hike Up Inferno Cone
The elsewhere twin: a short, steep cinder-cone climb (0.4 mi round-trip, 164 ft) on gravel-like cinders with open, exposed heat. Same kit thesis as Sunset Crater — abrasive shoe, seal the collar, sun for dark reflective rock — different state, same volcanic grammar.

Smartwatch + Analog
Watch Desk
Two lanes on the wrist: a durable trail computer for cinder-cone navigation and heat windows, and a Christopher Ward C63 Sealander Automatic on rubber that shrugs abrasive dust without a dress bracelet. Pair them. Volcanic days do not need polished metal scraping scoria.
Smartwatch
COROS Apex 2
Trail computer — dual-frequency GNSS, long battery, knurled crown, nylon strap that sheds grit better than a soaked silicone band. Photographed: Apex 2 Black as linked.
DC Rainmaker’s in-depth: long battery and a training platform built for mountain days. OutdoorGearLab and Road Trail Run land on the same lane — durable, glove-friendly crown, and GPS that holds up under canopy better than the first Apex generation.
DC Rainmaker — COROS Apex 2 / Apex 2 Pro · OutdoorGearLab · Road Trail Run
Why Apex 2 on cinder: Exposed volcanic loops want breadcrumbs and battery without Fēnix bulk. Differentiated from Pace 3 dawn days, Fēnix 8 soft-sand maps, Enduro 3 Sedona, and Vertix 2S technical rock.

Christopher Ward C63 Sealander
39 mm go-anywhere automatic — Sellita movement, 150 m WR, black dial, curved-end rubber sports strap. Photographed: C63 Sealander Automatic on rubber (C63-39ADA4-S00K0-RK).
Worn & Wound on the Sealander line: Christopher Ward’s “go-anywhere, do-anything” contemporary sports watch — simple, versatile, and built to leave the dress bracelet home. Fratello hands-on notes the black curved-end rubber strap as a solid sports option for the updated C63.
Worn & Wound · Fratello — Christopher Ward C63 Sealander
Why C63 on cinder: Rubber sports strap for abrasive dusty volcanic days — no bracelet links grinding scoria grit. Fresh analog lane; not a Ball watch; not Marathon GSAR; not the C60 Trident already used elsewhere.
Pair them. Apex 2 for maps, splits, and the cinder-cone route. C63 Sealander on rubber for time-only presence when the phone stays in the vest. GPS for the effort. Analog for the ash.
