Scarpa Spin Ultra 2 Review: 4mm Drop, 28/24mm Stack

Disclosure: TrainingPlan has not hands-on tested this exact model. This research-based review uses Scarpa US and UK exact-model pages plus two independent exact-model reviews. No Amazon US listing is currently verified for publication.

Quick Verdict

The Scarpa Spin Ultra 2 is a current high-cushion trail shoe for longer efforts. It uses SC-TPEE Spring Foam, a recycled-mesh upper with bio-based TPU overlays, and a Vibram Velox Max 2 outsole using Megagrip rubber. Scarpa publishes 10.2 ounces for men's EU42, 8.8 ounces for women's EU38, 28/24mm geometry, a 4mm drop, and a current MSRP: $189 US price.

This is a protective, controlled trail platform, not an especially soft maximal shoe. Independent testers describe secure traction and a firm ride, while some find the fit long or narrow. The old article's 6mm drop, 34/28mm stack, and invented “I-Spring” name described neither the exact geometry nor the actual foam.

Key Specifications

Scarpa US's men's exact page confirms 290g, 4mm drop, the foam, upper, outsole, and MSRP: $189 price. Its women's page supplies the 250g/8.8-ounce reference. Scarpa UK's product page establishes 28/24mm geometry.

What Changed

The old record listed 6mm drop, 10.4-ounce men's weight, 34/28mm stack, and “Supercritical I-Spring foam.” The exact model uses 4mm, 10.2 ounces, 28/24mm, and SC-TPEE Spring Foam. Those corrections now align the catalog and article.

The old Amazon listing audit returned only a generic page title, so the ASIN was not verified against Spin Ultra 2. It is removed from publication and from the dormant URL map. This protects against confusion with the original Spin Ultra or other Spin models.

Ride and Intended Use

Spring Foam is a supercritical TPEE formulation designed to balance resilience and consistency. At 28/24mm, the shoe is not extraordinarily tall, yet Scarpa categorizes its cushioning as high within the line. The platform feels firm and protected, with enough forefoot structure for rocks and long trail descents.

iRunFar's review measured a slightly lighter 9.9-ounce men's sample and described good long-distance versatility. The Vibram compound and 4mm lugs suit mixed mountain surfaces without becoming a deep-mud specialist. The trail-shoe guide covers more terrain-specific choices.

Fit and Sizing

Scarpa sells the Spin Ultra 2 in standard width. Independent feedback indicates a secure, sometimes narrow performance shape. iRunFar found its sample roughly a half size long compared with other brands, while Run to the Finish reported generally true sizing for its tester. Brand conversions, sample gender, and foot shape likely contribute.

Start with Scarpa's own size chart and compare adjacent sizes if possible. Check toe clearance downhill, midfoot pressure, and heel movement with trail socks. The shoe-fit guide explains why a longer shoe is not necessarily a wider shoe.

What Works Well

The outsole package is the strongest feature. Vibram Megagrip has a strong wet/dry reputation, and the Velox Max 2 pattern uses enough lug depth for varied trails without making the shoe unmanageable on short firm sections. The upper combines protective overlays with recycled content, while the 4mm geometry keeps the stance relatively connected.

Tradeoffs

Runners seeking plush softness may find the ride firm. The standard last may exclude wider feet, and long sizing complicates online purchasing. At 10.2 ounces, it is reasonably weighted for protection but not a featherweight racer.

Price evidence differs: Run to the Finish's early review listed MSRP: $179, while Scarpa currently displays MSRP: $189. The runtime follows the current manufacturer price and records the early discrepancy. No model-specific mileage lifespan is claimed; use the replacement guide.

Who Should Consider This Shoe

Consider Spin Ultra 2 for long mixed-to-technical trails when you prefer firm protection, 4mm geometry, and Vibram traction. It best suits runners whose feet match Scarpa's secure standard last.

Who Should Look Elsewhere

Look elsewhere for a labeled wide size, plush maximal softness, ultralight racing, or 6mm-plus lugs for deep mud. Fit-sensitive buyers should avoid final-sale stock without a try-on.

Cross-Brand Comparison

The Merrell Agility Peak 5 is broader and uses 5mm lugs plus a rock plate. The HOKA Speedgoat 6 is more rockered. Spin Ultra 2 is lower, firmer, and distinctly Scarpa-shaped.

Same-Brand Comparison

The Scarpa Ribelle Run 2 adds 6mm lugs and a tighter technical frame. The Scarpa Golden Gate 2 ATR is better suited to road-to-trail transitions. Spin Ultra 2 occupies the long-trail middle.

Value

Use MSRP: $189 as current US benchmark. Value depends on fit certainty and whether its specific firm/Vibram package suits local terrain. Compare actual delivered prices and return terms, not an early review's price alone.

Final Verdict

Scarpa Spin Ultra 2 is a 4mm-drop, 28/24mm long-distance trail shoe with firm Spring Foam and strong Vibram grip. The corrected model is compelling for precise-fit trail runners, but not a universal plush ultra shoe.
