Northwave Extreme RR 2 GTX Winter Road Boots
The Northwave Extreme RR 2 GTX brings a whole new level in winter boots for cycling. Designed to cope with the very coldest temperatures you’ll encounter, they keep your feet warm and insulated even at -15°C and are cleverly engineered to transfer every watt of power through to your pedals feeling just as positive as your summer race shoes while also providing the snuggest, warmest most even fit available. With a unique X-Frame® cabling system you can fine tune fit with just one SLW2 rotor which pulls evenly over the top of your foot while the Extreme RR GTX Climaflex collar provides a sock-like feel that simultaneously provides unprecedented mobility and total protection from the weather.
With a wind and waterproof barrier that keeps your feet warm and cosy the Climaflex collar is free from fussy overlaps and Velcro, extending seamlessly into the boot the soft, highly insulating thermal Neoprene and elastic Gore-Tex Rattler® membrane protects your feet from the cold in key areas.

Mr Howard Very good and reasonably quick overseas delivery. Product as described and will be worn home tonight. Will do more business with Merlin in future. So far the shoes have been great. Normally size 48 Sidi, these fit larger and are truer to size. I am a 47. Room for two or three layers as required. Worn down to zero degrees C so far with 2 pairs of merino socks with no cold feet. Sweat wasn't as bad as I thought it would be either - hardly any. They are comfortable and I will be buying a pair for mountain biking as well.
kenneth If you`re looking at these then you`re probably like me, fed up with cold wet feet, I've tried different socks loads of covers none of which are waterproof and after a couple of hours cold feet. Then I had an epiphany, the penny dropped, I don't use my summer gloves with covers on in winter I use my winter gloves, so I bit the bullet and ordered these. No more cold wet feet the only place for the water to get in is at the top, a pair of 4 inch gripgrab gaiters sorted that. Now size, I like my shoes quite tight and a 45.5 in sidi is just right which equates to a 44 in these. A little awkward to get on and off first time out but after a few times its a piece of cake. Look the part and I highly recommend them.
