Castelli Gregge 15 Sock - AW21

The Castelli Gregge 15 sock is a stylish super-soft longer length sock. Perfect for the colder months they are made from a clever Merino wool blend to keep you warm and comfortable. These striped socks feature a 15cm cuff and are available in a variety of cool colours.


  • Merino wool blend
  • Full-length thicker footbed for extra warmth
  • 15cm cuff
Mark Nice socks with a higher cuff which is what I was after although they seem a bit thin for an autumn/winter sock. Love the silver/grey colour scheme and will probably be OK down to about 2 or 3 degrees. Any colder and I think they might struggle to keep my feet warm.
JFW Really comfortable socks that look great too !
Mark Nice and warm
Mr king Great socks keeps toes warm on colder rides
Wex Lovely winter sock, nice thickness and super comfy!
Allan Great socks, have multiple pairs, good for cool days but will swap for merino when it gets colder
Mr Kerry Excellent warm sock that comes up a bit higher on the calf. The wool is really soft too!
Nat Nice long warm socks for cooler day, size fits ok
Matt Lawrence Warm and cosy
Mr Jones Great looking pair of socks. Vibrant orange and blue straight out of the pack. After 1 wash on cold water cycle, color wasn’t so vibrant anymore. Could be Tide detergent? Anyway highly recommended. Socks are not thin and quite comfortable
James Small/medium perfect fit (size 42 EUR)
Andy from MK Nice warm socks for the winter. Ordered 2XL even though im onlt size 8/42. Not overly big on first wear and shrunk to correct size on 1st wash. Great service and price as usual from Merlin
DavidJ I wear size 40.5 Sidi Shot & sizing is good. No holes or loose threads. I wear the merino socks from +3 to +12 degrees celsius. I washed the socks in hot water & sizing is still accurate. Great pricing
Andy from MK I ordered the XL even though I have size 7 feet but as per all Castelli kit, they came up smaller. Fit very well despite being for a much larger foot. Socks seem pretty warm and comfy. Excellent price and service from Merlin as usual.
Mr. Tim Nice sock, good quality item.
