I bought these because I love my old RS Pro shorts but I was disappointed today when I rode 55 miles. I kept slipping forward on the saddle (didn’t happen two days ago with different shorts and 45 miles).My butt rarely ever hurts but today was painful after about 30 miles.I do like the fit of these shorts but now I’m stuck with them. Will save for short rides.I ordered these bike shorts based on a review about the superiority of the chamois. The chamois is great, the padding was awesome. However, there are rough seams in this product that leave a mark and worse. I was on a 100 mile ride and had to change out these shorts for another pair at mile 60 due to the pain that began around mile 30. I had raw and painful skin where the seam bit into me. I will spare you the photo! The particular seam that got me was the one that holds the chamois in place in the back of the shorts. If you are going to use these for rides around 30 miles or less they might work (I will limit my rides in these shorts to 25 miles) but it is a shame that a product that is so expensive has these design flaws.The shipping was really fast (3 days earlier). I haven't ride with it yet but for now it feels comfortable... feels a bit awkward when standind. They're very soft and the ''pillow'' is perfectly think. But it's a bit tight at the end of the short... the rubber band is a bit disturbing for me. It feels like a great quality. I'd say they'll be fine for at least 2 or 3 summers. And for the size, I usually wear small, but after reading a few comments, I've descided to buy a medium. It was a right descition, they fit perfect. (I'm 170cm and 63kg). So I suggest that you buy one size larger than you usually do.Was glad i ordered a size up.....(usually a small, i ordered a medium) i can't tell you how many specialized shorts i have and i loved this pad!!I I was worried because of the price but they are so comfortable! Not disappointed..... rode 30 miles the first time i wore them we no discomfort.Great Product Great QualityI already own two one-piece and two two-piece tri kits from Sugoi which I love, so I thought I'd try the cycling shorts. They run a little smaller (too tight), and all the seat padding was too much for me; I already have a gel seat on my bike. So I'll be exchanging these for triathlon shorts instead, but they're excellent quality and the vendor service was great!I bought the exact same short in the same size last spring on Amazon. The first pair of mediums fit great and I loved them so much I decided to get a second pair. The second pair was cut a lot smaller from the first. There is no way they were supposed to be a medium fit. I returned them and got the large and they fit somewhat better but still cut too small for their size. I won't be buying Sugoi products online anymore. Only in a store where I can try them on first.Either the shorts are mismarked or there is another problem, but they are way too small. I have several medium Sugoi shorts (exact same product, type) and they fit fine. Unhappy with my purchase.小さくて穿けません。ムリムリムリ・・・・・・・・・・・・・。
