Hit the road this Winter in the Sidi Hydro GTX. This road shoe offers many features straight from Sidi's performance road models, plus an insulating Neoprene cuff and breathable Gore-Tex membrane to keep feet warm and dry. Billowed tongue provides extra comfort and cold weather protection.

Additional features:

  • Millennium III carbon composite sole
  • Lorica upper
  • Three High Security Velcro® brand straps
  • Compatible with three-bolt road cleats

Note: If you are using Shimano SPD-SL pedals, it is recommended that you use the Shimano SPD-SL 10mm cleat fixing bolt set as the standard 8.5mm Shimano bolts have a tendency to strip the threads of Sidi shoes.

Been using Sidi Hydro's this winter and they have held up great. With temps in the low 30's, I wear a liner and a wool sock and for 2 hrs have no issue with cold feet. Warm from the start and comfortable on the ride I recommend these highly. I did replace the insert, which is substandard with a Specialized insert and the shoes fit like a glove

Performance and warmth for winter riding- worth it!

I have suffered from frozen toes wearing booties over my road shoes when riding at temps below 40' F so I am predisposed to liking these winter shoes. They are expensive but I think worth it, if only because they simplify getting ready to go for a winter ride. I have only added covers (toe or full) on the coldest days, so one less step getting ready for most rides and they feel great. The fit is a little roomier than the same size SIDI in a road shoe but that allows for a heavier sock. I've had good success with the Castelli merino (gregge)in combination with these shoes and had great control, pedal feel and haven't frozen my toes yet this season.

Better than booties
by Dhm

These are definitely better than booties but pale in comparison to the no longer available Lake CX. I could wear those comfortably in 7F. These are fine with wool socks at freezing, but they're not insulated and don't come far above the ankles. The ankle Velcro doesn't stay firm. I'm already worried about how they'll handle less than 12F or freezing rain.

Nevertheless, these will keep me warmer and last longer than booties.

Sidi Hydro GTX is an exceptionally comfortable and practical winter shoe.

Sidi Hydro GTX is my only shoe for winter riding. I have it in the Mt. bike version as well, but prefer the road shoe. The Hydro GTX is quite comfortable and roomy. Be careful in sizing. I normally wear a 42.5 in Sidi shoes (8.5-9 US size) and was naturally concerned whether the 42 sidi would be too small. 42 was perfect, plenty of room, even with a heavy wool sock, such as Defeet Woolie Boolie. I have ridden the Hydros in temperature ranges of high 30 degrees to mid 50 degrees. I usually add a toe cover in temps below 40.
