ION Bike Footwear

Frequently Asked Questions

• How should I size ION mountain bike shoes?

  ION sizing tends to run slightly large, so many riders size down one size and try shoes on with the socks they plan to ride in. ION models are built for a snug heel fit without toe or instep pressure points, so check that your heel is locked while your toes have a little room; verify comfort while clipped in for best fit.
• Which closure system is best for my riding: BOA L6, Quick Lace, or lace + hook-and-loop?

  Choose by priority: the BOA Fit System (L6 dial) gives micro-adjustable, one-handed tensioning and the dial-on-tongue placement reduces breakage risk in crashes, making it great for aggressive or technical riding. Lace + hook-and-loop combos deliver multi-zone adjustability for a personalized fit, while Quick Lace offers fast single-hand operation and easy release for convenience on the trail.
• Are ION shoes compatible with mountain bike cleats and how do they perform when walking?

  ION shoes use a standard 2-bolt cleat plate for mountain-bike SPD-style systems and maintain a high level of pedal feedback thanks to torsional construction. Outsoles use SupTraction Rubber with Pin-Tonic 2.0 tread and dedicated climbing/pedal zones, which provide reliable grip and durability when you need to hike-a-bike.
• How does the Rascal AMP compare to the Rascal Select BOA?

  The Rascal AMP is a trail-oriented, all-terrain shoe tuned for balanced climbing grip and pedaling performance, while the Rascal Select BOA is tailored toward downhill and race-focused riding with a cleat placed slightly further back, increased stiffness, and the BOA L6 dial for precise fit. The Select adds reinforced protection and a stiffer platform for aggressive descents, whereas the AMP favors a more versatile feel on mixed terrain.
• What protection and materials do ION shoes use to withstand aggressive riding?

  ION uppers use robust PU with textile mesh and rubberized heel/toe caps for abrasion resistance, paired with an EVA midsole and Ortholite Eco Plush insole for cushioning and comfort. Impact-absorbing foams and Sas-Tec Level 1 (EN 1612-2) multi-impact pads provide ankle and toe protection, while torsional construction and the SupTraction outsole improve control and longevity on rough trails.
