Super ergonomic. My previous saddle have a geometrical/flat design and I'll felt its edges in every downstroke. Quite annoying.Selle Italia more organic shapes makes it unnoticeable.

Excellent saddle and a repeat purchase. Went from L3 to S3 and what a difference millimetres make. Premium saddle and material, durability over weight penalty.

Decided to try this saddle after hearing the S3 size has a tendency to fit many riders. Have had issues with wider boost style saddles as they have created pressure on my sit bones, but the this narrower model seems to fit my behind well.

Great looking saddle. The channel is comfortable. The material is grippier on bibs than I'm used to so you don't slide around as much. Any adjustments to your seated position requires elevating and then sitting back down again, which is harder than just sliding back. Shipping took a while but TradeInn customer service and the prices make it totally worth it. Love shopping here.
Compared to everywhere else I have seen this, it's a great price. Easy normal fitting and much better than my old saddle. Was recommended by a friend, so far so good
Saddles are pretty subjective, but this thing is great for me. I guess of note, I'm 5' 11", 152 pounds, lean build, and I'm always on a narrow saddle. I went with the S3 size and it's narrow and still supports me. What I'm more impressed with is the ability for me to roll forward more than usual. My test is usually if I try to puppy paw, how I feel doing it, and I can do it all day long on this saddle with a 10cm bar drop ,too. No issue. I stretch my back out during long rides and now I can roll more forward and have no discomfort. Great saddle. And the surface isn't slippery either, which is a nice bonus, some saddles are slippery. Comparison saddles - Prologo Scratch M5 (decent, but I feel it pushes me forward more than the SLR Boost), Pro Stealth saddle - also ... MoreSaddles are pretty subjective, but this thing is great for me.

Comparison saddles - Prologo Scratch M5 (decent, but I feel it pushes me forward more than the SLR Boost), Pro Stealth saddle - also good, but same deal, I feel it pushes me forward due to the sudden wing hitting my hamstrings, various others. Closest I got to this in comfort was a San Marco Aspide in narrow, which is really narrow and I have tons of clearance with it.
Fast delivery for Romania. The saddle looks very good. Waiting to try it out and then come back with a fitting review.
Selle Italia SLR Boost is a quality saddle at an affordable price point. I've had this saddle on three road bikes and find all-day comfort is the norm. Easy to install and adjust.
Very comfortable. Yet to do a long ride (100km+) but around 50km rides very smooth and better than my giant original saddle. The gap in the middle makes it less aggressive on soft parts.
Really like how comfortable this saddle is for short and long rides. Quite soft and has good cushioning. Worth mentioning: my sit bone width is 110 mm, and the saddle size is L3 (145 mm) — it was the right pick after a bike fit.
