Cobalt Reactor Blue Racing Motorcycle Boots

The Cobalt Reactor is the most overtly technical boot in the Zeesmoto® race-inspired range: a full-height cobalt blue, black and silver boot built around split shin plates with a silver centre structure. The split-plate arrangement is what lets a tall boot flex at the ankle at all — a single-piece shin shell is rigid, so the shin is divided into sections that move relative to each other as you go up on the pegs.

Design details

• Colour: Cobalt Blue / Black / Silver
• Shin construction: split shin plates with silver centre structure
• Entry and adjustment: offset side micro-adjust straps
• Lower construction: ventilated instep panels and a sculpted heel cage
• Best for: technical sport and track-style riding

About the micro-adjust straps

The side straps are offset rather than stacked vertically, which spreads the clamping load across the calf instead of concentrating it in one band. Set them once for your normal riding sock and leave them — they are for calibrating fit, not for getting the boot on and off every time.

Fit and sizing

Ten sizes, EU 39 through EU 48, with UK and US conversions listed on each variant. Select your normal motorcycle footwear size using the store's established EU / UK / US conversion labels. If you are between sizes or wear thick riding socks, consider the larger size. Try them with the socks you actually ride in; a boot fitted over a thin cotton sock will be uncomfortably tight over a winter weight one.

Care

Wipe clean after use, dry naturally away from direct heat, and apply only care products suitable for the upper materials. The ventilated instep panels will collect road grit — brush them out rather than soaking the boot. This original unbranded design makes no independent waterproofing, impact-rating, abrasion-rating, track-homologation, or certification claim.
