These work relatively well for bike shoes, better than the insoles that come with the bike shoes. They don't give you much of any cushioning in bike shoes as they would with a pair of tennis shoes, about as hard as the insoles that came with the bike shoes(bike shoes have a hard base, so the only cushioning you get is in the insole.), if you have "hot spot" issues with the piar of bike shoes, it maybe better to get a pair of the fat version insoles, if you have enough space in the shoe for them, these slim insoles won't get rid of that. The arch in these are a little bit more flexible than I had expected, compared to other arched insoles.

For insole fit in a bike shoe, bike shoes tend to run 1-3 sizes smaller over tennis shoes, so you may have to trim them to fit. My pair of shoes are a size 13, I got a size 12 insole, and the fit in the shoe is about as tight as you can get it without the insole bunching up in the shoe. For regular shoes I wear a size 11.5 to 12 for most pairs of shoes(in extra wide, 4e width.). My bike shoes probably run at around a standard wide width(2e) for the brand of shoe, which is a "tad" narrow.

I always thought foot pain after 5-ish miles of running was normal. My feet were absolutely wrecked after my first ultra (50K). Then I found these.

No longer feel like my feet are collapsing in the middle after a few miles. Ran 47.5 miles as part of a 24h tag team and my feet felt great! Even though these are pretty easy to swap between shoes (they're just insoles, after all), I still bought two more pairs so I could put one in my cycling shoes and leave one set in each of my most frequently used long-distance running shoes.

I've been cycling for over forty years and these are definitely the best insoles I have ever had in a pair of cycling shoes.

When it comes to cycling, I have problematic feet. They're wide, so I either have to find wide shoes (rare), or wear a half size to a full size up to get enough width to prevent my toes from being squeezed. I also have high arches and a weak ankle (the result of an injury many years ago). Without a massive amount of arch support, my weak ankle allows my foot to roll inward effecting both my foot's position on the pedal and my pedaling motion. In recent years I've taken to putting plastic arch supports beneath the stock insoles in my shoes. This has helped, but not solved, my problems and keeping the supports in place is a pain.

I did some research and found a suggestion regarding metatarsal support for cycling insoles. If you don't know what this looks like, it takes the form of a "bump" in the insole directly behind the ball of the foot. I did some more research and found excellent reviews and pictures of the Icebug insoles. I decided to give them a try.

They're pricey but, out of the box, you can tell they are well designed and well made. I bought a size 12 US to fit a size 47 Shimano road cycling shoe and they fit with minimal trimming on both sides of the toes. The length was perfect. The arch and metatarsal bump are both very pronounced. They look like they'd be uncomfortable, but they conform to my feet perfectly.

And they seem to work. I only have two thirty mile rides with them so far, but my foot comfort is much improved and I don't have to fool with separate arch supports. If things continue to go well, I'm going to buy a second pair for my mountain bike shoes.

I use these in cycling sandals and other water-tolerant bike shoes with flat pedals while navigating my prop drive/pedaled catamaran on long 30-40 mile day trips on the ocean. My feet have become intolerant of narrow shoes, and I have developed some forefoot neuropathy after decades of cycling. These tolerate frequent drenching without the adhesives separating, are thin enough to take minimal space inside a shoe, have the metatarsal bump, and a decent heel cup for stability. They work. Not as padded as thicker insoles, but I need maximum toe box space inside my shoes. I'd run the thicker version if I could, but most cycling purpose shoes that can tolerate immersion run a bit narrow, so I need something thin.

These are the only insoles that I have ever found that both support the way that I need and fit inside of my roller skates. I have high arches and sesamoiditis. These keep me skating comfortably. I don't know what Id do without them!
