Comfortable to wear and waterproof I'm a 'AGATT' guy so I usually wear MX boots offroad and roadrace full boots on the street. I was flying to rent a bike for 11 days and needed to pack light. I bought these to wear on the 8 hour flight and walk around. The boots are well made and very comfortable to wear all day. Last 3 days of my trip pouring rain. They never got wet inside which surprised me because they are short. Easy to clean up and wear home. Good purchase. June 14, 2016
Comfortable and Dry in the Cold, Rain, and Heat. I've had these boots for a short time now and they've performed very well. I live in Iowa where the weather has ranged from 28° to 80° in the last three weeks. My feet stay comfortable at 70mph in the cold, rain, heat and humidity. They are very stylish in jeans, especially my Rev-It Tornado 2 pants, and don't look out of place in dress pants at the office. I'm also told the reflective features really pop at night. As Anthony mentions in the video break-down there are rubber nubs in the toe for tactical feedback with the shifter. In my opinion these were designed too narrow as they began sheering off in the first week. There are currently 3 missing from my left toe. However unfortunate, this is of little concern to me as I feel no difference engaging the shifter. Still, -1 star for sheering off so soon. All-in-all I'm happy with these boots and I absolutely recommend them to anybody looking for great protection, comfort, and style. April 19, 2016
sizing this product was tight initially. the shoe needed to be wider. January 19, 2016
Good choice for lightweight GTX boots The boots are exactly as advertised: sturdier and more protective than soft riding shoes (sneakers), yet lightweight and unobtrusive compared to full sport riding boots. I was especially interested in the inclusion of Gore-Tex, and that works as you would expect. Of course, the leather--which is of a very good quality--does get wet when riding in a strong downpour, but the interior stays dry so long as you are careful to protect the top edge with your riding pants. I added a DWR coating (Granger's), so now the outside sheds water as well. The shifter panel offers good tactile feedback, and the soles have a fine level of grip on the pegs. As others have mentioned, these are actually very comfortable to wear off the bike. I wear mine around the office when casual shoes will suffice. In fact, I hate to take them off and put on boring regular shoes! Highly recommended. January 2, 2016
Great commuting Shoe Use this protective shoe for commuting to work. Provides a decent amount of protection, but as expected not as much as a full height boot will. Gore-tex allows the shoe to breath, but keeps the foot dry as long as your riding pants are long enough to cover the top of the shoe. Decent product great for commuting and casual rides, and as always, Revzilla was fast in getting it here. November 9, 2015
A riding shoe but also an all day sneaker I would definitely recommend these riding shoes! The are very comfortable to wear all day on or off the bike. I wore them a solid 11 hours when we rode to Barber for the vintage festival. I walked around in them all day. Just like wearing a high top sneaker. You do need to wear a good thick sock because the fit is a tad bit wide but manageable. I would buy these again in a heartbeat. Don't shy away from these because of the price. You are getting what you pay for. Ride safe! October 26, 2015
Good riding shoe I tried 4 different riding shoes before settling with the Sidi Mythos Gore Tex. The others would pinch my instep when walking or were too wide or too uncomfortable to walk in after riding. These are not the best at everything but they are pretty good at most everything. I wish they would offer these with some ventilation as they do get pretty warm on a hot day when you stop riding and are walking around in them, nothing you can't live with. The shoes are flexible enough to walk in comfortably and they are the correct width for my foot. They look good under a pair of jeans although I would like a stripe or something to break up all the black on the top of the shoe, but that s just me. I have noticed my feet are a little tired after spending a few hours in them but that is probably because they are not broken in yet. They offer good shifter feel with plenty of protection for the foot and ankle. Overall, I would recommend these and would probably buy them again if something happened to this pair. Sizing is spot on for me. I wear a size 10 or 10 1/2 and a 44 fit me perfectly. I use these when riding a 2006 Buell XB12ss Lightning long. September 7, 2015
Great Shoes These shoes are pretty amazing. I love the look and layout of these shoes. They're also gore-tex so they resist become muggy inside while keeping the water out. This may just be me because I know that I have good feet, but I am able to walk all over my school campus with these on (I put forcefield soles in them), and my feet don't hurt at all. They obviously aren't like walking on a cloud, but it's defiantly doable. They're not built for comfort, but they definitely aren't bad. Style, waterproof (breathable gore-tex), and sturdy protection is where these boots exceed. They get by with a passing C+ grade on comfort. Add an extra sole to the boot and you can bump comfort up to a respectable B. September 5, 2015
