Specifications:
Protective footwear for motorcyclists (EN 13634:2017)
Measure your foot length from the heel to the tip of your longest toe. Stand barefoot on a sheet of paper and distribute your weight evenly. Mark the very back of your heel and the tip of your longest toe, then measure the distance between those two points. Make sure you are standing straight, because the foot expands slightly under weight.

Eine Nummer größer
Die Stiefel sind hervorragend.
Allerdings hatte ich zuvor Stiefel einer anderen Marke in Größe 42. Normalerweise trage ich bei regulären Schuhen Größe 41,5. Die Sidi Stiefel fallen sehr schmal aus. Mit Größe 43 komme ich gut zurecht.
Bezüglich des Versands könnte dieser optimiert werden. Was jedoch definitiv beschleunigt werden sollte, ist der Rückerstattungsprozess. Meine erste Bestellung musste ich retournieren und dementsprechend eine neue aufgeben. Dies führte zu einer doppelten Belastung, und die Rückerstattung dauerte nahezu 14 Tage.

Great quality and mobility.
Bought this SIDI REX AIR after buying a Alpinestars Supertech. The Sidi REX AIR is better at mobility and fits true to size. My feet is 24,5cm and I got number 40EU (25,2cm) at SIDI official website guide. Fits perfectly with lots of feel and mobility. The other brand was bigger and with no mobility and less feel. Great service from FC-Moto. Danke!
Die Stiefel sehen toll aus und machen einen sehr guten Eindruck was die Verarbeitung angeht. Allerdings sind sie in meinen Augen sehr unbequem. Sie drücken schon nach kurzer Zeit an der Wade.

Excellent fit, clever concept
These are a replacement for older sidi Vertigo Air boots,
and they are truly a next generation improvement: excellent tight fit, good finish, Italian elegance, fully adjustable,
and the perforated leather is great in summer.
Order one size above your shoe size.
