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.

Sehr gute Stiefel für die Rennstrecke!
Ich habe mir die Stiefel hauptsächlich gekauft um auf der Rennstrecke zu fahren. Da sie aber ein Knick Gelenk haben, lassen die sich laufen wie normale Schuhe was wirklich ziemlich erstaunlich ist. Die Stiefel sind teuer aber meine Füße sind mir mehr wert… meiner Meinung nach sehr guter Schutz und Komfort in einem Stiefel. Ich würde sie wieder kaufen.
