Inline skating
Hi, Myra! I love inline skating. I actually bought my skates over 6 years ago. They are rollerblades and cost $120. My advice is to search for skates that feel really comfortable first. If they don't feel good you will not do it. Try rentals to try different models.
I definately recommend rollerblades because of the automatic brake system (the brake pad is replaceble and takes a while to wear out), especially if you are new to inline skating and need help stopping. I believe they are the only ones who have this system. I am fairly advanced (I skate fast and can do turns) but I love that brake and it makes me feel more comfortable skating with that feature, knowing I can stop.
I have had to change my wheels a few times, but the boot has held up well. I will look into Trevor's advice of using street hockey wheels. Also, you can prolong your wheels by rotating them, because the middle ones never get as worn as the front ones. Try and consider what you want out of your skates, too. Racing skates are great if you "feel the need for speed", but they are usually more expensive. Also, you don't get as good a work out, either, because it is easier to move faster so you don't work out as hard. I went skating with a friend and I was huffing and puffing to keep up with her. Later I realized she had faster skates (or maybe I'm not as advandced as I thought!). I want a happy medium between fun speed and a good work out.
But, if speed is what you want, you might go more often or longer, so it might end up the same. Which reminds me, my husband upgraded my bearings on my skate when I last changed wheels. I skate faster than before, so an intially slower skate can be upgraded later to a faster skate.
If you are new, get pads and practise falling on them. You feel much better and more confident knowing a spill won't hurt (hopefully, not much anyway). Supposedly, there are new gel filled pads that conform to your limbs and are super comfortable, but I haven't found them yet, so if anyone knows where to find them, let me know, please.
Inline skating is great if you also like to downhill ski because the weight shifts are the same and you use a lot of the same muscles. I live in Florida and try to go skiing every year and it is a great way to get ready for it.
I hope this helps!
