SIDI Apex Boots 4.7 5 59 59
Great short boots The boot just come in the day before yesterday and I wore them for a short trip yesterday This boots look awesome for me under riding pants especially riding sport-bike. The boot feel stiff since they haven't broken-in just yet but as I noticed the boot never restrict my movement. Getting in and out is easy which makes them practical, however even with the vents fully open I still; get sweaty feet. Eventhough it's a short boot but judging from the exterior I can rest assure that my foot is well protected August 17, 2016
BUY THEM. DONT SHOP.BUY THEM I already have a pair of "full size" a-stars (the smx 6) and love them but wanted a pair of boots i could wear if i was just throwing on jeans and a jacket not wearing full leathers etc. i dont like stuffing jeans in full length boots. SO i tried these out and am very happy with them. they have great protection, good air flow, they're comfortable... overall GREAT product. NOTE! for me they run a bit large i normally wear US size 10.5 (uk 46 i believe) i got these in a US 10 and they're perfect... keep that in mind. August 10, 2016
Great Boots I was looking for some commuting shoes/boots but with the highest protection available without compromising the look and the style, basically something that have lots of protection but that it doesn't look like I'm walking around with race boots. The side Apex were the right choice it has all the protection and at first sight it blends just fine with a pair of jeans or regular pants. After riding daily with them for little over two weeks, I am satisfied with my purchase, ventilation is OK but my feet still get hot, they feel a little stiff at the beginning but after a couple of days they broke in just fine. If your looking for a commuting boot or simply a boot that you can wear under a pair of jeans and walk around with them without compromising protection these boots are a great choice. Great quality boots. August 5, 2016
CONDUCTED TONS OF RESEARCH - PLEASED WITH CHOICE FIT: As other reviews have stated there is a break in period. I highly suggest taking full advantage of RevZilla's suggestion and walk around in them inside to make sure they are the right fit for you before jumping on the bike and heading out. I was a slightly hesitant in the beginning because my feet felt like they were falling a sleep and also fairly tight but after a little time that changed. Warning: after wearing them the bottom of my calfs hurt slightly the next day after wearing them, although this might have something to due with me not being use to wearing a riding style boot, the wider opening at the top is different from what I'm use to. In my opinion it was a little strange getting use to because of the location of the top of the boots.It fell mid-to-lower-calf level (around the Achilles tendon) but being able to tuck my pants in (riding or jeans) is IMO a valuable feature with a short style riding boot. At this point I've done approximately 150 miles while wearing them and they feel great! I was concerned about how they would perform on normal roads in city traffic due to the smooth appearance of the soles but once again I no complaints there either, I haven't had a single issue even when unintentionally stopping on what would normally be slick areas on the road such as markers, painting, and oil spots left behind by vehicles. I've noticed now that they have been better broken in they aren't uncomfortable walking around in either. Although it did take a little while for me to get use to the "balance" due to the protection "tang" inside the sole. SAFETY: I personnaly feel more confident riding now that I have the ankle and heel protection, when you consider a large number of riders sustain foot injuries in crashes its nice to have the protection. I feel safer; I'm do however hope I will never have the need to test the true capabilities of the boot but either way the added safety features are great. I also think that the versatility of the boot is unmatched, being able to change out parts of the boot if damaged is IMO an invaluable added feature. Riding conditions have changed dramatically for me; there have been many recent changes. Not only have I moved from the West Coast to the East Coast but I've also changed the style of bike (I went from a sport and cruiser to a super sport). In addition I've never had to really lean my bike at more extreme angles before but now corners and turns in this particular area are exceedingly tight. For me having the toe sliders also add a sense of added safety increasing my confidence overall. I truly believe you can't put a price on safety and the price is amazing especially when you consider the quality of the product you're getting. I don't doubt if I am able to get several years of enjoyment out of this pair of boots. I'll be the first to admit that I'm no longer 10-foot tall and bullet proof, not like I was as a younger U.S. Marine. CONS: There really aren't any however, if I were to change something it would be the air circulation, it is less than I'd like. Sidi has changed the location of inlets on their newer designs but overall the ventilation isn't horrible whatsoever. ADDITIONAL COMMENTS: This is my first pair of riding boots and I did a ton of research prior to choosing this particular brand and model. By a ton I mean I spent so much time researching and comparing the different brands and models that my wife actually commented on it and finally pleaded with me to "just pick one already". I'm extremely pleased and comforted with my decision. SHIPPING: RevZilla has impressed me consistently. My boots arrived the very next day. Luckily they had my size in a local warehouse so it was very fast. Communication & Customer Service: After making the purchase I felt extremely confident that I would be pleased with my purchase. The representatives at RevZilla were awesome and they gave guidance and assistance determining what would meet my needs during the decision making process. GREAT PRICE, HIGH QUALITY PRODUCT, AND VERY PLEASED OVERALL. July 1, 2016
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
