Icebug Run

Frequently Asked Questions

• How do I choose between BUGrip and RB9X traction for winter running?

  BUGrip uses 11–16 carbide steel studs and deep lugs for unrivaled grip on ice and hard-packed snow (seen on Myr BUGrip and NewRun BUGrip GTX), making it the go-to for icy roads and trails. RB9X is a sticky rubber compound (used on Järv RB9X and Acceleritas 9 RB9X) that excels on wet rock, slush and mixed terrain without studs and is more asphalt-friendly. Choose BUGrip when ice is the dominant hazard and RB9X when you need versatility on varied winter trails.
• What should I look for in fit and drop when buying Icebug running shoes?

  Icebug running shoes generally offer a road-like fit with a roomy toe box and secure lockdown; plan for a slightly firmer ride than plush road trainers and consider your usual running length or half-size up if you run with thick socks. Drop varies by model—Järv is around 4mm, Arcus about 6mm, and Myr about 8mm—so pick a lower drop for a more natural mid/forefoot gait and a higher drop if you prefer heel cushioning. Always account for stack height and intended terrain when deciding between models.
• Are Icebug GORE‑TEX models fully waterproof for winter runs?

  GORE‑TEX variants like Arcus 2 BUGrip/RB9X GTX and NewRun BUGrip GTX add a waterproof membrane that keeps feet dry in snow, slush, and wet conditions. The membrane reduces breathability compared with non‑Gore‑Tex uppers, so on long, very sweaty efforts you may notice warmer feet. Choose GTX for sustained wet or slushy conditions and non‑GTX water‑resistant uppers if you prioritize breathability and quicker drying on mixed winter routes.
• How do Icebug shoes perform for long-distance winter trail running and what cushioning can I expect?

  Icebug uses eTPU midsoles that deliver a firmer, springy feel—stable and durable for long winter outings but less plush than maximal road trainers. Models like Arcus 2 RB9X GTX and Acceleritas 9 RB9X provide higher stack and more endurance comfort while preserving ground feel and the traction needed on mixed winter terrain. Expect a balance of responsiveness and durability rather than soft, cloudlike cushioning.
• How does the Myr BUGrip compare to the Järv RB9X for winter running?

  The Myr BUGrip is a studded shoe (carbide steel studs, aggressive lug pattern) with about an 8mm drop, optimized for icy roads and packed-snow conditions where maximum slip resistance is required. The Järv RB9X uses the sticky RB9X rubber, has a lower ~4mm drop, and is tuned for mixed trails, wet rocks and faster technical runs where studs would be unnecessary. Pick the Myr for prioritized ice performance and the Järv for versatility and better performance on wet, non-icy surfaces.
