Looking to upgrade your drivetrain? Then look no further. The new Shimano 105 Di2 R7100 groupset brings Di2 shifting to a new affordable pricepoint. With functions and tech inherited directly from their DURA-ACE and ULTEGRA drivetrains, 105 Di2 is the culmination of years of research and development. Thanks to a shared Di2 platform, sophisticated ergonomics, 105-optimised gear combinations and an exceptional brake system, Shimano 105 Di2 marks a new era of affordable performance.
Going electronic also lets you shift lightning-fast under load – such as when climbing or sprinting, customise how you shift and change gear without performance loss. Wireless shifting brings a clean cockpit free of shift wires and ports. While the internal Di2 battery is concealed in the seat post or frameset.
The new 12-speed cassette is the same width as Shimano's previous 11-speed cassette, so the space between each cog is narrower. This means shifts so smooth you’ll barely notice them.
Key Features:
- Wireless Di2 Shift Levers for a cleaner cockpit with 3 year battery life
- Lightning-fast precision shifts at the touch of a button
- Revised STI ergonomics
- 10% extra brake pad clearance
- Battery life of up to 1000km between charges
- Fully customiable shifting via the Shimano E-TUBE app

⭐⭐⭐⭐⭐ Clean Look, Comfortable Ride
Size: 11.5 Wide, Color: Woodbury Handstain
The Cole Haan Men’s GrandPro Tennis sneakers are a perfect mix of laid-back and polished — the kind of shoe you can wear everywhere without thinking too hard about it.
Right off the bat, the design is subtle but refined. They’re minimalist enough to pair with jeans and a hoodie, but they also work with chinos and a button-down for a more put-together look. The “tennis” aesthetic keeps it classic without feeling like you’re wearing athletic shoes.
Comfort is where these really shine. They’re lightweight and cushioned in all the right places, so long walks, errands, or standing around at events don’t end with sore feet. There’s no stiff break-in period — they feel good from the first wear. The sole has just the right balance of support and flexibility, which makes them easy to wear all day.
The materials feel good too — soft, sturdy, and not flimsy. They hold up well after repeated wear and still look fresh even after a few outings. They don’t crease or scuff up excessively, which is always nice.
If I had to point out a downside, it’s that they’re not performance sneakers for athletics — but that’s not what they’re meant to be. They’re lifestyle shoes that look great and feel great for everyday wear.
Overall, a solid go-to sneaker that elevates casual outfits and keeps comfort front and center. Easy recommend if you want versatile kicks that stay stylish without being loud.
I was able to pick up this particular pair here on Amazon for 50 bucks, 56 total with everything and honestly I’m still scratching my head in that deal. I mean my New Balance were 70 bucks or something like that.
These are brown leather, sophisticated and comfortable, just amazing shoes. I get compliments all the time.

Size seems spot on shoe is beautiful
Size: 12, Color: White
These are beautiful shoes. A great cross between the ubiquitous flat as a board shoes like vans and tennis shoes. More comfortable than the super flat shoes and more formal than sneakers. Very soft leather. Not much arch support and I don't know if an insert would fit well. I am between an 11.5 and 12 in most brands (actual foot length from heel to tip of big toe is 11 and 1/8 inches). These fit perfectly in a 12 with room for comfort. An 11.5 probably would fit but snugly. I do not agree that they should be sized down at least based on my experience. If you can get these for under eighty dollars like I did they are well worth it. I'll be wearing them all summer.

Weightless, well made. But there are problems with size
Size: 8.5, Color: White
I bought it for a teenager, for size 81/2. This, according to the dimensions on the page, is 25.9 centimeters. They came, the size was indicated correctly, but they are large for the child. Very large. They fit me, size 10. The child is disappointed.
Well made, look neat on the foot. Almost weightless
But I can't give the maximum rating. I wish the seller to deal with the size grid.
