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.
- 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.

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.
