These are definitely made for the race track but after a bit of break in and learning how to adjust them properly they are great. Probably not waterproof. Nice bit of ventilation on hot days. Seem to have top shelf crash protection.

普段は26㎝の靴だが、試着せずEUR43（JPN27.5㎝）のブーツを購入。つま先が余り指が遊んでいる状態だったが、インソールで調整したらぴったり。

I have owned SIDI's for over 20 yrs and loved them. I may be used to a broken in boot, but initial fitment is quite painful and going to take some break in.The length is correct for a 46/11.5 boot, but the toe cap area narrows quickly (Height & Width) with little wiggle room.If your foot runs wide the outter support & vent really digs into the side of the foot. (Darn coof extra weight) I wore them inside for about an hour and just had to take them off. I will try again with thinner sock.Materials and construction is what you would expect from a SIDI boot - top-of-the-line! Looks great too

A fantastic bit of kit, especially if you have narrow feet

I ride in Florida. These are cool. Look nice. Strong lightweight protection for your feet/ankles. Definitely superior to mid boots. Sidis are a little tight due to a low toe box. The air cutoff doesn't mean much with vented fabric. Recommend use with Klim vented socks to protect your shins.

This is the worst quality I’ve ever seen. I honestly can’t tell how much glue they even put. Both boots had the sole peel off at the same time while I was out on the track! Fortunately it was starting to rain so I was going much slower than usual but if I had gone out and ridden hard without noticing this that could have been super dangerous. This almost ruined my track day and getting my race license. I was running back and forth between classes and exams to find epoxy and zip ties to fix this so that I could go out for my evaluation session.I’m assuming since they failed simultaneously these boots peeled off because of the heat it - was 111F the day before at the track and also hot that day but that is not an excusable failure mode or a corner case. People ride in hot places all the time and your boots are next to really hot parts of the bike.Last thing I need on the track is to be wondering if I won’t be able to reach my shifter because my foot peg is stuck in between the sole and base of the shoe...

Spitzen Verarbeitung! Ohne meine Einlagen viel zu groß (Höhe/ dicke vom Fuß), mit Einlagen jedoch perfekt. Belüftung bringt spürbar was. Leider fingen sie seit der 3. Ausfahrt beim gehen an zu quietschen ( bei meinem Kollegen ebenfalls), muss man halt schmieren
