SIDI Apex Boots 4.7 5 55 55
exelent good product i recommend good ventilation confortable feel safe June 14, 2016
Great low cut boots The Apex Boot was my first stab at a low cut "street" use only boot. Sizing was spot on, I wear a 9.5 and ordered the 43. I was a little nervous about the break in period for the boots but after wearing them for a full day the fit and feel just kept improving. You still get great feedback from the pegs and the sole is very grippy. Vent is a nice added feature as well. I would highly recommend theses boots. June 13, 2016
Comfort Boots are still fairly new. They fit great in the foot and are comfortable. The top part of the boot will take some time to break in, as it makes the top of my calf sore at the moment. I'm glad to have finally bought a pair. April 29, 2016
Great Boot I wanted a boot that I could use for my daily commute that wasn't as extreme as a full race boot but offered more protection than riding sneakers. In come the Sidi Apex boots. Out of the box, these look great. They have a single zipper that runs all the way down the side of the boot which makes them very easy to put on or take off. No laces that might get caught up on your pegs. The boots run pretty much true to size but are a little snug. In terms of protection, I haven't "tested" these but they look and feel great. The are like mini race boots. Hard toe, hard sole, inside and outside ankle protection, toe slider and hard heel cup. I feel that if something were to happen, these would protect my feet very well from both being crushed or rashed up from sliding. They have little vents that open and close although I've only had them open. They move air, but not compared to smaller lighter sneakers. But it's a compromise I'm willing to make. My feet haven't been hot yet, but the SoCal summer months are coming so we'll see. They're not very good to walk any sort of distance in. They're almost like short ski boots. They really don't have a lot of flex. I keep a pair of shoes at the office and just change when I'm here. All in all, I feel that these are a great value for the price and level of protection offered. March 22, 2016
Great Boot Great Boot!...Like all good boots, it must be broken in...Haven't crashed with them and I hope I never do, but they give a feeling of confidence! February 23, 2016
style is top notch Its been almost a month and have just broken in. Walkig in them takes a bit to getting use to. January 19, 2016
Sweet Street Boots These boots are a great choice for those wanting some upgraded protection from a tennis shoe and not wanting the hassle of strapping on a full-on race boot when you want run out the bike for a gallon of milk. I'd say these are excellent 3-season boots for moderate climates like Phoenix where you can wear them from April-November no problem without feeling the cold too much. These boots fit fairly true to size as I wear a 10.5-11 street shoe and went with a size 45. These do not come with insoles so I slipped in a basic Vasque insole. They still fit fine (albeit snug) but I could walk around all day at a bike show if I wanted to without problems. I have worn them for about 200 miles now and at work for 3-4 hours at a time. I tried on the Dianese and A-Stars but these boots stood out with looks and quality even if they are a bit more then the equivalent A-Stars model. These boots are high quality as are most SIDI products, good fit, and they look awesome. These boots are fairly low cut and do let the wind in around the ankle below my Aerostitch suit so if you want a winter boot go with a full-length cut boot. November 3, 2015
Excellent lower cut boot I have owned numerous SIDI motorcycle boots and default to them as my choice for footwear. I currently ride with a SIDI Vertigo boot, the Apex is essentially the same boot but in a lower cut. Their fit is true to size; I wear a 11.5 shoe and have found SIDI boots in an 11.5 / 45 to fit perfectly. They look awesome, offer great protection, and feel comfortable. August 4, 2015
