So iLL

Frequently Asked Questions

• What sets So iLL climbing shoes apart in terms of design and performance?

  So iLL blends minimalist, gym-to-crag aesthetics with technical features like Vibram XS Grip and Dark Matter rubber, tensioned lasts, and vegan microsuede uppers to minimize stretch and improve comfort. Their models prioritize fit precision (asymmetry, downturn, heel lockdown) and a balance of sensitivity and durability that appeals to both performance climbers and lifestyle-oriented users.
• How do the Roam Soft and Roam Rigid compare—when should I choose each?

  The Roam Soft has no midsole for maximum flexibility and sensitivity, making it ideal for steep roofs, rounding, and situations where feel matters most. The Roam Rigid shares the same vegan microsuede upper and Vibram XS Grip but adds a midsole for stiffness and shape stability, so it's better for edging and technical routes that demand support. Choose Soft for slab/roof sensitivity and Rigid when you need edge security and longer-wear structure.
• How should I size So iLL shoes like the Street and Roam for bouldering versus all-day comfort?

  The Street is an aggressive, downturned performance shoe and is typically worn about a half-size up from your normal street shoes if you want high-performance sensitivity; many climbers still size it down relative to comfort shoes for bouldering sessions. Roam models are designed to be more true-to-size and offer tensioning that accommodates a range of foot shapes—opt for your normal climbing size for all-day gym comfort or slightly smaller for performance-focused use. Always check heel and toe lockdown and consider your foot volume when choosing between aggressive and comfort-oriented fits.
• What rubber compounds and construction features does So iLL use, and how do they affect performance?

  So iLL commonly uses Vibram XS Grip and their Dark Matter rubber for high stickiness and reliable edging; softer compounds boost friction on roofs while firmer midsoles and split outsoles influence stiffness and flex. Downturn and asymmetry increase toe precision for overhung terrain, whereas minimal or no midsoles favor sensitivity on slabs and rounded features. The combination of vegan microsuede uppers and specific outsole choices lets you match a model to your preferred terrain and performance trade-offs.
• Are So iLL Features Kit holds suitable for commercial gyms and home walls?

  Yes, Features Kit holds are large, ergonomic pieces (slopers, pinches, pockets, positives) made from durable, high-friction rubber designed for repeated use and a wide range of wall angles. Their sizing and grip profile make them versatile for route setters who want comfortable pinches and positive holds that translate well between training and recreational settings. They’re built for durability and varied setting styles rather than delicate, competition-only textures.
