How to ask about skiing in Hokkaido

Hello,

I'm traveling to Hokkaido soon for a ski trip. I speak a little Japanese, but I was wondering if a native speaker could help me translate (Romanized Japanese is fine) the following questions:

(1) I'd like a larger size of ski boots
(2) I'd like a smaller size of ski boots
(3) I'd like to ask about skiing with an instructor.

Many thanks!

No need translate.
Ski site staff will understand such easy phrases and words.

If really want to...
これより 大きいサイズの靴に お願いできますか？
これより 小さいサイズの靴に お願いできますか？
スキーについて　インストラクターに 直接 訊きたいです。
Copy all phrases to Google translate then click "speaker" icon.

This is better. http://voicetext.jp/
(same way copy all and click speaker icon)
"通常版" is normal "natural pronunciation" than Google.

Thank you!
